Chinese character stroke problem!

Correction: The stroke order of "mouth" is: vertical, horizontal and horizontal. The second pen has no hook.

The difference between a hook and a hook mainly depends on whether the bottom is horizontally sealed. Generally speaking, there are some uncapped strokes, such as "Tong, Gang", some uncapped strokes, such as "Tian, Ri", and other uncapped strokes, such as "Jian, Bei".
