Is the martial arts coach particularly cruel? Is it common for coaches to hit people and swear, and it's to the death? When students are disobedient.

I can't help it. Generally, coaches are very kind. Only when you make mistakes and keep teaching and practice lazily will he be like this! The coach beat you and scolded you for your own good, and it will not kill you. Can you still give you a hard time after listening to him? What the martial arts school is really afraid of is the fighting between students, so it's hard to say.
