Why do my friends in WeChat circle change their avatars, and I don't show them here?

I will be happy to answer this question for you in the future.

Your problem is that your WeChat circle of friends has changed, so it won't be displayed here.

Personally, I think you should change your circle of friends here. It's no use changing your circle of friends that you can't change!

Changing the avatar should be in your place, that is to say, open WeChat, and then click on the avatar to change it, which is effective.

Mobile phone use knowledge

Mobile phones can't be separated from us all day long, and there will be the shadow of mobile phones everywhere in our lives. From getting up in the morning to going to bed at night, the mobile phone is always with us. Call, surf the Internet, take photos, send Weibo, anything, but if we can't use the mobile phone correctly, it will do harm to our health. Today, the cloud mobile phone will tell you about the harm and precautions of using mobile phones to our health.

First, try to put your mobile phone in your pocket as little as possible.

I believe most people will put their mobile phones in their pockets. In fact, this practice will do great harm to our health. According to the British "Times" report, Hungarian scientists found that men who often carry and use mobile phones can reduce their sperm count by as much as 30%. Medical experts point out that if the mobile phone is often hung on the waist or abdomen of the human body, the electromagnetic waves generated when it sends and receives signals will radiate to the sperm or eggs in the human body, which may affect the user's reproductive function. The British experimental report pointed out that mice irradiated by mobile phone microwave for 5 minutes will cause DNA damage; Long-term exposure of human sperm and eggs to microwave radiation from mobile phones may also cause DNA damage. So I still suggest that you put your mobile phone in your bag and try to stay away from your waist and abdomen. Therefore, mobile phone users should try to keep their mobile phones away from their waist and abdomen, and it is best to put them aside when users are in the office, at home or in the car.

Second, don't talk too long.

When people use mobile phones, they will send radio waves to the transmitting base station, and the human body will absorb these radio waves more or less. These radio waves are the radiation of mobile phones. Generally speaking, mobile phones radiate less when they are in standby and more when they are talking. When the mobile phone number is dialed but not connected, the radiation is the largest, and the radiation amount is about three times that of standby. These radiations may change human tissues and adversely affect human health. Moreover, long-term contact of the mobile phone with the ears and face may cause skin allergic reaction and produce a red or itchy rash, which is called "mobile phone dermatitis". Therefore, I hope that everyone will make as few phone calls as possible, spend as little time as possible when making phone calls, or choose to answer the phone with headphones to reduce the direct damage of radiation to the brain. However, it is recommended that users use a landline to make calls when they have one.

Third, be careful when playing with your mobile phone in the toilet.

Playing with mobile phones in the toilet will contaminate them with a lot of bacteria. And when you accidentally drop your mobile phone in the toilet, it will be miserable. But if the phone is flooded, please remember not to press any button, especially to turn it off (when you press any action, the water will immediately flow away with the circuit board). The correct way is to immediately open the cover, directly remove the battery, and directly force the power off to protect the motherboard from water. Bian Xiao suggested that you should try not to use your mobile phone when you are squatting. Even if you don't fall into the toilet, it's not good to delay other colleagues from going to the toilet in the company.

Fourth, it is not appropriate to play mobile phones when eating.

If you eat and play at the same time, it is very bad for the digestive system. Because you are distracted, food will be swallowed without chewing, causing a burden on your stomach, and inattention will affect saliva secretion. Saliva and chewing are the first step in normal digestion, which will increase the burden on the stomach and lead to stomach problems over time. In addition, there are a lot of bacteria on the mobile phone. According to British researchers and experts, the current situation of people using mobile phones and 30 mobile phone samples were investigated. The results show that among the 63 million mobile phones used in the UK, 6,543,800+0.47 million pose a health threat. The average amount of bacteria carried by a mobile phone is 18 times that of the flush handle in the men's toilet. Moreover, many tested mobile phones carry a high amount of bacteria, which is enough to cause severe abdominal pain symptoms for users. Although these bacteria will not make people sick immediately, the high number of bacteria carried on mobile phones indicates that people's hygiene habits are worrying and will also become the soil for other bacteria to breed.

5. Don't answer the phone when the phone is charging!

It's not my hand in the photo. Is a young man who works as a business manager in an insurance company in India. He answered the phone more than ten days ago when the phone was still connected to the charger. After a few seconds, a lot of current passed through the mobile phone, and the young man was thrown to the ground. When his family found out, his fingers were burned, his heartbeat was weak and he was unconscious. After being rushed to the hospital, the doctor pronounced him dead. Mobile phone is the most commonly used modern invention at present. However, we should also be alert to the danger of instrument death. No matter whether you have made a phone call while charging, you should pay more attention in the future and try not to make a phone call while charging. After all, there is only one life.

6. Don't put your mobile phone on the pillow when you sleep.

Whether it's sending a text message to your beloved at night or playing a boring game and reading a novel before going to bed, put your mobile phone on your pillow. This will cause great damage to the head! Haas experts say that mobile phone radiation is harmful to people's heads, which will cause dysfunction of people's central nervous system and cause headaches.

The above is a person who changed his avatar to your friend in the WeChat circle of friends, and then, that is to say, this question is not displayed here. This is very simple, I hope it can help you and I hope you can adopt it.

Finally, I wish you health, happiness and good luck.
