What multiple of sunscreen (SPF, PA) is suitable for the current weather in Chongqing?

SPF 15, PA+ is enough, and it is used in weather with weak ultraviolet rays, such as winter in Chongqing.

No sun doesn't mean no ultraviolet rays. In fact, you should protect yourself from the sun at all times. I just read these theories in a book the other day. They can't be wrong. Girls should pay attention to protect their skin, but the landlord should not wear too thick!
