When I first got up in the morning, after a night's rest, my reproductive function was vigorous and my beard grew quickly. Even if you shave it, you can vaguely see the stubble growing in the afternoon. After about half an hour's consumption, the androgen in our body is not so strong, and the growth rate of beard is reduced. If we shave again, it won't grow out soon.
The suggestion is university. If you are a person who develops very early, it doesn't matter if you shave in high school. Now I think stubble is actually quite sexy, as long as it doesn't mess up.
