I am 16 years old and have a lot of beard and mustache. I just shaved it today. I don’t know if there are any tips or things to pay attention to. Is there any way to fix it?

Boy, this is a normal physiological phenomenon based on personal development. First of all, congratulations, your male hormone secretion is normal. Secondly, don’t try to inhibit the growth of your beard, because beard is a physiological characteristic of men and cannot be removed naturally. Unless you go for hair removal. Moreover, a beard is a man's decoration. It is very sexy to be able to trim a good-looking beard. Finally, what you need to pay attention to is that if you don't want your beard to grow too fast, don't hang it too often. The more you hang it, the faster it will grow.
