There are always some headaches for parents as children grow up, such as seeing children who like to fight with others;
When you're at home and you're getting along well with your family, you start stuttering and blushing when you go out in front of other adults;
When you're at home and you're getting along well with your family, you start stuttering and blushing when you go out in front of other adults;
Children start to cry when they see their parents, or they like to hit people;
I usually get a lot of inquiries from moms and dads about similar issues, and at the core of these questions is the issue of "children's sense of security.
The increasing emphasis on security with children shows how important it is for children's future development, even for their whole lives.
So, first of all, we need to get a proper understanding of what security is, and first of all, not to attribute all the problems to security, otherwise we cannot solve them.
Erickson's theory of stages of personality development suggests that children's crisis in stage 1 is trust and doubt.
The primary influence in this stage comes from the mother. If the parent is able to meet the child's needs during this stage, the child develops an initial sense of security; if the mother denies the child's needs, the child develops distrust.
Trust is therefore the key to building a sense of security. Children who are secure are more independent, confident, get along with others, and are more likely to feel happy; whereas children who lack or lack security in childhood are prone to low self-esteem, sensitivity, suspicion, and過度活躍.
After knowing what safety is and the importance of feeling safe, I'm sure parents are more concerned about this aspect of their children, so how can we help our children build a sense of safety?
First, understand why your child is afraid. If you want your child to be afraid to talk when faced with a stranger, first of all, to give you an example to help you understand better, then instead of feeling ashamed and mandating that your child must put on a big smile, you can squat down and touch your child and ask him or her what the reason is for being afraid. This is because the act of touching the child's body will make him feel physically safer; the act of asking why and analyzing it will allow the child to discover what his or her irrational beliefs are and what "I" should be doing to be good.
As in the lemon example, some children cry when they leave their parents because once they leave, they think that the environment and people around them will hurt them if mom leaves. In reality, this is not dangerous at all.
So this is a good time for mom to try to let other family members take over, both to get the child out of the habit of relying on the mother and to make the child aware that other people can be a dependent role for him or her.
In addition, parents can slowly try to allow their children to be alone in a space, but they need to communicate to their children in advance where they are going and how long it will take them to return. The mother who disappears suddenly, on the other hand, can create a great deal of insecurity in the child.
Similarly, for children who use violence to solve problems, parents need to check the atmosphere in the home for violence before solving the problem.
That's because seeing parents fighting with each other may not seem wrong to us, but it can become a form of violence in the eyes of the child.
This is because it's not a good idea to have a parent who is violent, or to impose a scolding parenting style on the child, so that the child thinks that violence is the only way to solve the problem.
Nurturing a child's sense of security requires parents to start acting now. There are many ways to do this, and the attitude and behavior of teaching children is just as important.

1. Try to choose milk powder made from raw cow's milk
The source and production of milk is closer to that of milk powder, which can be made from fresh milk and only needs to go through a dry drying process during the production of milk powder. This type of milk powder is classified as raw milk or skim milk.
2. Choose a milk powder with higher whey protein content
If your child is more prone to constipation, mothers should not immediately choose two formulas for their children when they are breastfeeding for more than six months.
One formula contains a little less calcium, iron and zinc, but the child bb便便 has already started to add supplemental food, so basically it does not affect much. Children can digest and absorb milk powder that is not easily constipated, so a section of milk powder has a high nutrient absorption rate and can meet the nutritional needs of children over seven months of age.
3 Choose a formula with high OPO structural fat.
OPO structural fat, also known as 1,3-dioleic acid-2-palmitic acid triglyceride, can soften children's stools, prevent calcium soap formation, and promote children's nutrient absorption. To prevent constipation in children, when choosing a formula, try to choose a formula with a higher content of OPO structural fat.
The term most nutrients found in the nutrition chart is generally 1,3-dioleate 2-palmitoyl triglyceride. When buying milk powder, you can compare which content will be higher.
Choose a formula with a high content of oligogalactose.
The main thing to look at is the nutritional content in the table, but of course there are some units of oligogalactose in milligrams and some grams, so pay attention to the conversion.
Some formulas also add oligofructose, which is also useful for preventing constipation dietary fiber. It is best to have both of these ingredients, and both are high in content. It can be compared with several kinds of milk powder.

First: Recognize your baby's needs
The experts say that the best formula for your child is the best formula. When changing your baby's formula, the first thing you need to do is find out if your baby really needs to change.
However, if the baby has uncomfortable 3號奶粉 reactions to some formulas, such as diarrhea, constipation, slow weight and height growth, etc., the mother should consider changing the formula. The mother should consider changing the formula for her baby.
Second, don't change the formula too often
When changing formula, parents should choose the appropriate grade of formula based on the age of the baby. Infant formula (0ー6 months) is usually called paragraph 1, older infant formula (6ー12 months) is paragraph 2, and infant formula (12ー36 months) is paragraph 3.
Third: pay attention to the method of changing formula
Mix one-third of the new formula with two-thirds of the old formula and give the baby a few days to get used to it. If darling has no adverse reactions, mix 1/2 of the new formula with 1/2 of the old formula and adjust for a few days. Finally, replace two-thirds of the old formula with the new formula, adjust for two or three days, and then replace it completely with the new formula.
Step 4: Avoid wrong timing
If you don't get the details right during a formula change, it's easy to put an unnecessary strain on your baby's stomach.

Beef contains sarcosine, which can increase muscles and strengthen strength. Vitamin B6 can enhance immunity and is suitable for people who are taking care of patients after surgery and illness. It can also be 去疤膏推薦 with beef and red dates to help muscle growth and promote wound healing.
Aloe vera is a natural antibiotic that can relieve pain, stop bleeding, and tighten wounds. It is also a catalyst that can accelerate the healing of injured skin. "Traditional Chinese Medicine" records its 除疤方法, tissue repair and skin protection functions.
Compared with ordinary vegetables, tomatoes are rich in natural antioxidants and vitamin C. Vitamin C can promote the biosynthesis of bone collagen, which is conducive to faster healing of tissue wounds, and enhances the body's anti-stress ability and immunity to the external environment. The premise is to eat raw, because the vitamin C in tomatoes is unstable and easily oxidized and decomposed during processing.
Drinking a little honey is great for wound healing. 除疤膏推薦, honey can also be applied directly to the skin or wound. In doing so, it has the effects of reducing inflammation, relieving pain, stopping bleeding, reducing edema, and promoting wound healing.
Trotter is rich in zinc and collagen. Zinc deficiency will reduce the function of fibroblasts. Therefore, more collagen should be added at this time to speed up the wound healing.
Generally speaking, eating black fish is good for wound recovery, but sea bass is most suitable for operators. For example, patients with anemia or diabetes should learn to start eating sea bass before the operation if they are not injured, and eat it after the operation, which is very helpful for the healing time of the wound. Chinese medicine believes that seabass is warm and sweet in nature, has the functions of invigorating the spleen and stomach, nourishing the liver and kidney, relieving cough and reducing phlegm.
What can't you eat for wound healing?
1. You can't eat soy sauce for wounds, which may cause scars on the wound.
2. Do not eat spicy and irritating foods, such as peppers. These foods are easy to get angry and cause inflammation of the wound.
3. Injury can not eat edible fungus food, such as mushrooms, shiitake mushrooms, etc. Because these foods are mostly high-protein foods, eating too much can easily cause irritability, which is not conducive to recovery, and people who usually have headaches, dizziness and other symptoms should eat as little mushroom food as possible.
4. Do not eat marine fishery foods, such as hairtail, yellow croaker, pomfret, mussel meat, shrimp, crabs and other aquatic products. Most of them are cold and fishy, which affects wound healing to a certain extent.
5. Do not eat fruits such as peaches and apricots. These fruits are easier to catch fire when eaten, and almonds are easier to eat to damage bones and muscles, which will have a certain impact on wound healing.
In the process of wound healing, you should avoid eating chicken heads, chicken wings, chicken feet, goose meat, pig head meat and other foods. These foods can easily cause irritation and affect the healing of the mouth.

These students who do not want to study in Japan, or who have long been in the mud, often ask some difficult questions. Today, we respond to such difficult questions one after another. As it is often said, "An 日語五十音 start is a wide success". If you understand the challenges below, you can get off to a perfect start. Shaping the proper outlook on learning is half the battle for success in the natural world.
Without further ado, let's go to the topic.
1、What is the purpose of learning N5課程?
Learning Japanese well will help you to get rid of "parallel time and space", and let him/her go in the world of China and Japan.
If you only use Japanese as the only special tool for students to make a living, you can choose mainly in translation, export and foreign trade, teaching and other industries.
If you integrate Japanese with other professional skills, such as programming, finance and accounting, Japanese animation, sales and marketing, you will also enter a road to become a master in the field.
2、I think there are many 日語會話班 characters in Japanese, is it very easy to learn?
Many people are likely to feel that there are a lot of Chinese characters in Japanese, so is it very easy to learn them in our country, but in my own work experience, at least at the level of writing and meaning of Chinese characters, we Chinese people have an advantage over foreigners who are not easy to use Chinese characters.
3、I want to learn Japanese, but I'm too busy at work, so I have little time to study every day.
Language expression is a professional skill that is accumulated over time, in fact, you don't need to take out a lot of time to learn, but only stipulate that you keep persevering. Then for the salaried people, it is important to be good at using your spare time, just take out thirty minutes a day, persistently learn for a year, and you will be improved!
In the end, or this saying, if you want to learn, nothing is a pretext, if you don't want to learn, which are all pretexts.
4, some people say Japanese "learning Japanese is laughing in, crying out" is that so?
Which newcomer to begin easy to learn after more difficult to call all of their own not to learn the pretext, language expression is a professional skill, it to the learner's situation, knowledge system, age are not much regulation, only need to persevere, nothing to learn not to understand. Naturally in learning, you will always encounter shortcomings, and this is the time when teachers must organize specific guidance for the group.
Learning language expression, there are a lot of items must be memorized, if you do not want to memorize, do not want to learn, do not want to figure out the syntactic structure of Japanese, it will naturally feel difficult to learn. Or this saying, step by step, there will always be certain gain.
5、How long will it take for me to pass N1 if I have a general certificate of qualification and don't have all the basic and generally only have non-working time to learn Japanese?
How long it takes to pass the level is different from person to person. According to the teacher's work experience, the average person who spends 1 or 2 hours a day to study well for 1.5 to 2 years should be able to pass the highest level N1. I personally do not approve of the way to break the N1 in 10 months raid, because the qualification is primary and secondary to learning the language, and the key is to improve your language expression ability. The certificate exam can be your overall goal of learning Japanese in stages, but it is not the key purpose of your study.
6、I want to learn Japanese, but I don't have any carefulness, so I want to ask how to persist in the end?
In fact, I would like to say that the thing of carefulness is to be gradually shaped, one very important point is the hobby of learning Japanese, generally speaking, people who want to learn Japanese are all interested in it or have a desire to learn it, plus a good natural environment for learning and a good model for learning, of course, they will have the patience to persistently learn it.
Therefore, hobby is the best teacher, although they are very vulgar, but it is very right.
7、I want to learn Japanese, can I learn it completely by myself, without enrolling in any training institution?
It is not highly recommended not to enroll in tutorial classes, because the language expression is something that, in fact, in short, you learn to use eventually, such as communication with people, in the case of novice beginners, your pronunciation only through self-learning words will have a certain lack, and that will immediately endanger your spoken English expression. Therefore, from the teacher's teaching experience, it is necessary to have a Japanese teacher to standardize your pronunciation in the case of new beginners.
Secondly, a fluent Japanese, English grammar is also important, if you simply read the contents of the book, without the teacher's summary and interpretation, very easy to learn and forget in addition, if you are enrolled in a tutorial class to learn words, in a class can find like-minded young people to learn together, so that their own learning is also a kind of promotion.
In general, you can learn through self-learning, but the difficulty factor is large, easy to lose direction. The expertise in the textbook is fragmented and has incorrect and systematic holes. If there is a teacher to guide, on the one hand, can help the guys immediately summarize, in addition to the guys can also have a catalytic effect on learning.

Listed here are step-by-step tips on using a stethoscope to hear your baby’s heartbeat:
1.Locate a tranquil locale. The quieter your environment, the better it’ll be to hear your baby’s heartbeat. Sit in a place by itself while using the television and radio off.
2.Lie down on the comfortable area. You can pay attention to your baby’s heartbeat in bed or lying over the sofa.
3Really feel all over your tummy and find your baby’s back again. Baby’s back can be an ideal place to listen to a fetal heartbeat. This segment within your tummy should really experience challenging, however sleek.
4.Spot the upper body piece on this location of your belly. Now it is possible to start to listen via the earpiece.
You could possibly not quickly listen to it. If this really is the case, bit by bit transfer the stethoscope up or down right until you’re in the position to pick up a seem. Fetal heartbeats can sound similar to a enjoy fetal doppler.
What to do when you simply cannot listen to the heartbeat?
Don’t stress should you simply cannot listen to your baby’s heartbeat. Making use of a stethoscope is one process for listening to a heartbeat at your home, but it is not often effective.
Your baby’s situation might make it tough to listen to, or else you might not be far adequate together within your pregnancy to detect a heartbeat that has a stethoscope. placenta placement can also create a change: Should you have an anterior placenta, the audio you’re on the lookout for could be more difficult to locate.
You can try once more at yet another time. Although, in case you have any worries, do not be reluctant to get in touch with your OB-GYN.
Your OB has probable read hundreds - otherwise 1000's - of heartbeats. Even though it is heartwarming (no pun intended) to hear your small one’s ticker within the comfort of your home, you should not use anything you hear - or do not hear - to diagnose any problems. Go away that to the doctor.
Listening to your unborn baby’s heartbeat for that 1st time is a thing you will never forget. An ultrasound can select u...

It's the annual September school season, are prospective students already excited in their hearts? Are there a lot of expectations for college life?
But in the case of everyone is happy for the upcoming college life, but there are many poor mountain students due to the lack of family pressure college tuition fees and secretly worried, and even only clutching the admission letter sad tears. But do not know that the country has long been two years ago to develop a plan program, never let all a student due to the family situation problems abandoned school. However, there are still many people are not clear how to get this kind of assistance, today Xiaotao on all the state funding and its reward methods listed out one by one, to help promote the poor mountain students, round the dream of youth!
A, interest-free installment national student loans
The national student loan application for processing is generally divided into two kinds of methods, one is the source of student loans, the other is the school national student loans. To put it plainly, the student loan is the national student loan that students apply for in their own residence after being admitted to the university, and the school national student loan is the national student loan that students apply for in the school according to the financial aid center of the school after being admitted to the school on time and reporting. The student source student loans are generally carried out by the cultural and educational institutions in charge of the student's place of residence, and the student must only bring along with his or her mother and father to the corresponding application address to carry out the application process, together with the letter of admission to this year's college entrance examination, identity documents, family register, and identity documents of his or her mother and father. Students should prepare their identity documents, photocopies of their family register, and photocopies of their parents' identity documents to the school's financial aid center before they enter the school. Some areas will likely continue to require students to show proof of their family's economic development, which is generally available from village committees (community committees) and street offices. And national student loans are not measured for loan interest until the student graduates from college.
scholarship for university overseas exchange/internship programme.
Second, the national state grants for poor students
The national grant is applied for by the students after all the normal reports of entering the school, according to the school. Generally, after entering the school all normal new semester start period will gradually to the big group will be issued to the relevant financial aid current policy notice, and easy to recruit to apply for the roster of students. The students to be applied for must write the application for the grant writing the reason for the application and their own family economic development status, family size status, family size health situation, etc., and submit to the school financial aid center for the first approval. After the first examination and approval, the school financial aid center will give the application form to the students who are approved for the first time to fill out, and at the same time submit their own documents proving the economic development of their families (for example: the low income guarantee certificate of the needy households, the certificate issued by the relevant department of the household registration, the low guarantee, the certificate of the disabled, the certificate of the surviving family members of the martyrs, etc.). The school's financial aid center will report to the higher leading authority for approval, and the school will upload the content of the financial aid student information into the national poor student database query after the audit is approved. The national scholarship is divided into three levels, the first grade of 4,000 yuan per year, the second grade of 3,000 yuan per year, and the third grade of 2,000 yuan per year. And the distribution is carried out in academic years, respectively, 2000 yuan, 1500 yuan and 1000 yuan per academic year.
Third, the company national scholarship
Many companies also have a corresponding financial aid current policy, and institutions of higher education to carry out collaboration, every year to take out part of the assets to finance part of the poor college students at home. The actual application process is different for various companies, so you can take a look at the circular document issued by the financial aid center of the school you belong to, and the document will be written clearly.
I. National scholarship
National scholarship is a kind of outstanding college student reward current policy opened by the state to better encourage college students to study seriously and forge ahead. Each higher education institution (full-time master's degree, undergraduate, college, and post school) is able to strongly recommend outstanding students to apply for the National Scholarship every year. The National Scholarship is dedicated to rewarding those students who excel in all aspects of personal performance, especially in the dimensions of practical community activities, independent innovation, and comprehensive ability, who have made great contributions to the basic construction of the school, and who have an examination score of not less than 85 in each subject of all examinations, an average examination score of not less than 90 in all subjects, and an examination score of not less than " Excellent", in the same condition of all other levels of standards to get the provincial "outstanding student party cadres", "three good students" priority selection. The national scholarship is RMB 8,000 per person per year, and the one-time payment will be credited to the student's personnel file.
National Classical Inspirational Scholarship
The National Classical Inspirational Scholarship is an outstanding college award policy opened by the state to better encourage poor college students to study seriously and struggle hard. It is mainly for full-time undergraduate students in higher education, college students, students in higher vocational colleges and universities, and students in the second year (sophomore year) and above classes who are open to apply for it. In order to apply for the National Classical Inspirational Scholarship, students should first have a record in the national database of poor college students, be diligent and active in various major performances in school, have excellent academic training results, and have no bad habits or bad habits. Application for processing according to each student after 5000 yuan per year, a one-time arrival and the distinction will be counted in the student's personnel file.
Third, the school scholarship
Each school is also to better encourage students to study seriously and the development of outstanding student scholarships, in which include but not limited to the three good students scholarship, outstanding student party cadres scholarship, the top ten group leader scholarship, the top ten group support scholarship. Students applying for the scholarship must have a high level of education and excellence in their studies and training, contribute to the school's infrastructure, and have no disciplinary infractions. The actual method of application varies from school to school, so you will need to read the relevant documents of your own school.
Company scholarships and organization scholarships
Scholarships are created by various companies and organizations in collaboration with colleges and universities. Companies and organizations offer scholarships for companies and organizations in order to create a good brand image for social development and to bring in high quality talents. Many companies also collaborate with colleges and universities to create company-ordered classes, in which the company gives scholarships to students and covers the cost of training for these students, authorizing them to be entrusted to the colleges and universities for shaping and working in the company immediately after graduation. The actual application process varies, so please refer to the relevant circulars.

Microphones are a very personal item for musicians, and there are often many factors to consider when choosing one. Again, there is no such thing as "one microphone is the best" among a wide variety of microphones. Each microphone has its own unique properties and uses, and produces a different sound quality. Let's learn about the 7 types of microphones in common use.
The term "moving coil" means that the coil of wire, which is closely connected to the diaphragm, is kept in motion in a magnetic field in response to changes in sound pressure, producing a current that varies in equal proportion to the amplitude of the sound wave, by which the sound signal becomes an electrical signal.
The coil of a moving-coil microphone cuts the magnetic field to produce current directly, so no power supply is required for a moving-coil microphone. The advantage of a dynamic microphone is its simplicity and practicality. The disadvantage is that the "dragging" of the coil makes the diaphragm less responsive to rapidly changing sound waves than other types of microphones.
It is difficult to get a dynamic microphone to pick up the high frequency part of the energy of the rubbers, but for picking up the sound of a solid base drum or snare drum, a dynamic microphone can perform satisfactorily. Moving-coil microphones are also commonly used to record the sound from electric guitar amps.
Moving coil microphones are often used to record the human voice, and it is largely a "traditional habit". The original condenser microphones were bulky and fragile. However, while there are many condenser microphones available today specifically for live vocals, their higher average price also often leads one to choose a mobile microphone that is equally good at its job.
Small-diaphragm condenser microphones
A condenser microphone is designed according to the principle of electrostatics. The diaphragm and the back plate form a capacitive unit, and the vibration of the diaphragm with the sound waves causes the potential difference between it and the back plate to change, turning the sound signal into an electrical signal. Capacitive microphones generally have built-in amplifiers because the output of the condenser unit is weak. Condenser microphones require external 48V phantom power or batteries.
The significance of choosing a small-diaphragm condenser microphone is that a small diaphragm of about 12 mm diameter is extremely sensitive to acoustic vibrations. The larger the vibrating diaphragm, the less sensitive it is to improper microphone sound, and the more pronounced the resonance will be.
If what you want is extremely accurate radio results, a small-diaphragm condenser microphone is the way to go. It's worth noting that a more accurate sound is not necessarily a more satisfying sound, and sometimes a more accurate sound sounds less dynamic and less powerful. However, if you want to record natural sounds realistically, a small-diaphragm condenser microphone should be your choice.
Diaphragm condenser microphones.
Before that, microphone manufacturers were not able to make the diaphragm so delicate, and all condenser microphones should be called "large-diaphragm condenser microphones". There was certainly no dividing line between what was a "large diaphragm" and what was a "small diaphragm". As mentioned earlier, a size of about 12mm can be called "small diaphragm", while a size of 24mm or more can be considered as "large diaphragm". When buying a microphone, we will find that some microphones that look very large have a surprisingly small internal diaphragm, so the size of the diaphragm is a parameter that needs special attention.
The advantage of this large-diaphragm condenser microphone is that it allows you to record a sound that you especially appreciate in the studio, but it is not the most natural, but its sound is thick and warm, no matter what sound is recorded is very comfortable.
The disadvantage is that the higher the sound frequency, the more obvious the directionality of the large-diaphragm condenser microphone becomes. There is no problem if the microphone is facing the radio, but if two microphones are used for stereo radio, the sound on the side may not work well.
Electronic tube microphones.
The design and production of this microphone can be traced back to the early days of condenser microphones. At that time, the built-in amplifiers of condenser microphones all used vacuum tubes because the application of transistors had not yet become popular on a large scale. Although there were some vacuum tube microphones used with small diaphragms before, most of the vacuum tube microphones we see today have large diaphragms inside.
The advantage of tube amplifiers is that they easily produce a pleasant distortion effect, or "warm sound". For sound, this warm distortion is often used as a panacea.
Unlike other types of microphones, tube microphones have become highly sought-after and often expensive due to the fact that the days of tubes are long gone.
Aluminum ribbon microphones.
An aluminum ribbon microphone is a special type of dynamic microphone. Usually, the diaphragm of a moving coil microphone is closely connected to the wire guide coil, and the microphone with aluminum piece is a combination of the diaphragm and the wire guide coil to form an aluminum ribbon (or metal ribbon). Because the aluminum ribbon is very thin, microphones with aluminum ribbons are sensitive to sound waves comparable to condenser microphones, although the sound of ordinary aluminum ribbon microphones is darker.
Aluminum ribbon microphones can record a clear and slightly darker sound in detail. In this way, they are often used in studios.
Aluminum ribbon microphones are generally fragile, and some brands have manuals that remind users to walk slower when holding an aluminum ribbon microphone on the radio so that the air doesn't pass over the microphone too fast and cause the ribbon to misalign.
Like mobile microphones, most aluminum microphones do not require an external power source (except for those with built-in amplifiers). However, the output of aluminum-banded microphones is generally smaller, so they work better with a preamp.
Electret microphone is a special kind of condenser microphone. It is well known that the principle of a condenser microphone is that the capacitor polarization charge changes, thus generating an electrical signal at both ends of the capacitor, which results in the conversion of sound signals. Electret material is a material that permanently preserves these charges after adding them. According to this principle, the electret material on the diaphragm or back plate can provide the constant voltage required by the condenser unit, thus eliminating the power supply portion of the microphone. However, the use of built-in microphone amplifiers still requires the use of battery or phantom power. It is important to note that electret microphones using batteries are less sensitive and less capable of handling maximum sound pressure.
Electret microphones are widely used in handheld devices due to their low cost and small size. Electret microphones with built-in FET preamplifiers can provide high quality performance. Many of the most accurate microphones in the world today are also electret microphones.
Piezoelectric microphones, also called crystal microphones, are based on the principle of using the piezoelectric effect of a certain material, i.e. sound causes deformation of the material and produces a change in voltage.
Currently piezoelectric microphones exist mainly in the form of contact microphones, of which guitar pickups are a typical example. A piezoelectric microphone receives physical vibrations directly from the source of the sound taken, rather than the sound wave vibrations in the air. This has the advantage of separating the sound of the instrument from the rest of the sound. However, the sound selected in this way will not be particularly realistic, so the application of piezoelectric microphones is also relatively limited.

Recently, the weather station issued a cold wave forecast. These days, we will clearly feel the temperature dropping a lot, even more than 15℃ in some areas. Now it is the high season of influenza again, plus the serious situation of the new crown epidemic, we should be extra careful. Assuming that you have the flu, some people may be overly worried and can go for nucleic acid testing. So what can you do to get better faster if it's really just the common flu?
You can quarantine yourself at home.

In addition to being able to identify the quality of the lamps and lanterns, you also need to follow some buying principles to make the lamps and lanterns more convenient to use and more in line with your own home environment. Below, I'll introduce the seven principles to follow when buying lamps and lanterns, to help you buy lamps and lanterns!
One, the principle of convenience
The vast majority of people have experienced the embarrassment of removing and replacing ceiling light bulbs in the living room: stepping on the dining room table, stepping on the table and chairs, crossing their heads ninety degrees, raising their arms over to the 2.5m or even higher canopy. When choosing lamps, be sure to consider the removal and replacement of electric bulbs convenient.
Second, the principle of safety
Be sure to choose reliable manufacturers of lamps and lanterns. Reliable goods are marked with the total load, according to the total load, can clearly apply is how much power of the electric bulb, especially in for double-headed ceiling lights more critical, namely: number × each electric bulb power = total load. In addition, wet washrooms, restaurants and kitchens should use moisture-proof lamps.
Three, simple principle
Lighting fixtures in the house should have the effect of painting the dragon. Overly complicated modeling design, overly complex flower pattern, are not suitable for the design of simple house.
Fourth, the principle of environmental protection and energy saving
Energy-saving bulbs save electricity, lighting fixtures degree and good, also will not release too much heat, available double-headed lamps and lanterns. Most energy-saving bulbs are standard spiral lamps, and ceiling lights have two kinds of specifications, one is standard, can apply energy-saving bulbs; one is non-normative, can not apply energy-saving bulbs. When choosing to pay attention to: most of the track spotlights are non-non-energy saving and environmentally friendly products.
Five, the principle of role
Along with the development trend of technology, the role of lamps and lanterns also want to diversify the direction of development, intelligent lighting systems are gradually entering everyone's home. Many lamps and lanterns give a variety of roles, some of this role is designed for games and entertainment programmes, some are designed for remote control programmes, to name but a few.
It is likely that we will come across some additional roles for a portion of the money in the case of choosing lamps, which will necessitate us to carry out our purchases in a way that integrates our specific situation to make our daily life more fashionable and trendy and comfortable.
Not the same application role of the house, should be installed not the same style, lighting fixtures degree of lighting. Large living room should be used bright, rich elegant lamps and lanterns; bedroom should take the lamps and lanterns that make people shake their eyes unconsciously in bed; children's room should take the lamps and lanterns with bright colours and rich transformation in style; bathroom should take the simple style of moisture-proof lamps and lanterns; restaurant kitchen should choose lamps and lanterns that are conducive to scrubbing and cleaning; some areas that must be unique major performance can also choose track spotlights.
Sixth, the principle of harmony
Lighting and the overall design style of the house to be in harmony, and the same house of a variety of lamps and lanterns, should maintain the colour harmony or style harmony. Such as wood panel walls, solid wood cabinets, wood top of the square living balcony, suitable for installation of square wooden lights; equipped with iron accessories table, galvanized pipe laminated glass dining table and dining chairs square over hall, suitable for installation of square galvanized pipe material ceiling lights; installed with gold cabinet door handles, gold track spotlights bedroom, suitable for containing gold decorative design lights.
