Have you found that in your circle of friends, the number of WeChat movements is particularly high in winter, but it is obviously reduced in summer?

This should have nothing to do with the season, but mainly with your amount of exercise. If the amount of exercise is large, there will be more natural steps, and if the amount of exercise is small, there will be fewer natural steps. Generally, people may walk less in winter, but they walk more these two days, so there will be obvious changes. Why else would this happen? They are all based on robot technology and transmitted to the server through mobile phones, so there should be no obvious seasonal changes, only related to the number of steps people walk.
