Do I still need to wear a cotton-padded jacket on February 20th?

February 20 is the solar term rain of the lunar calendar, and the temperature is still relatively low, especially in the northern region, which is still a few degrees below zero at night and only a few degrees during the day. Try to wear a cotton-padded jacket. The so-called spring covering autumn freezing, if you take off your winter clothes too early, it will cause a cold.

So it's better to cover it.
