What do you think about the fact that the caps of three cases of Bingfeng drinks in Xi 'an are frozen and flying?

1. Why do the caps of drinks freeze? When winter comes, many people wrap themselves tightly when they go out, because winter is very cold for people living in the northern region. Basically, everyone rarely goes out because it is too cold. Some ice-peak drinks bought by a wholesaler in Xi 'an even have their caps frozen off, and the caps fly directly from the bottle mouth of the drinks, and some drinks have been frozen. For such a thing, some people suspect that there may be a problem with the quality of the drinks, but the supplier said that these drinks were given relevant anti-freezing measures when they left the factory, which may be caused by improper preservation by the merchants. Such a thing also shows that the weather in Xi 'an is very cold.

2. Is it really cold in winter in 2.Xi? After watching the video of the passive flying of the beverage bottle cap, everyone said that Xi 'an was actually cold enough to fly the beverage bottle cap, so everyone must do a good job of cold protection and warmth when traveling. In fact, this kind of weather is not too cold for local people, because it is about MINUS 10 degrees, which is insignificant for the northeast where it is MINUS 20 or 30 degrees from time to time. And many places have central heating, so everyone can still resist such cold, but for some people in the south, such cold is obviously beyond the tolerance of some people, so for people in the south, the weather like Xi' an is really too cold.

Third, how to keep warm in winter? In fact, everyone has a variety of warm-keeping measures in winter, the most important of which is central heating. Because of central heating, basically everyone will not be frozen at home, and the temperature is similar to that in spring and autumn, but in any case, everyone needs to go out during work or study, so when going out, you must do a good job of cold protection and warmth, and don't feel warm at home and outside. For your health, you should wear more clothes, especially when you work outside for a long time. Once there is something wrong with the body, it will not only be painful, but also affect the normal life and work. Try not to travel by bike if you can, because the wind in winter is biting and the temperature is very low. If you take public transportation, you don't have to endure the cold. Go out in winter.
