Good people help me. My father practices Tai Chi. Now I find that he is possessed and doesn't want to work. I feel superior in martial arts.

Find a martial arts school nearby (Taekwondo, Sanda and the like, don't choose the Hua Quan Pavilion, don't get me wrong, there is no other meaning).

Have a good relationship with the coaches there (go there to learn martial arts, chat with the coaches more, take the initiative to train, greet the coaches on holidays, or send some small gifts)

Explain your father's situation to the coach in a month or two and ask the coach to meet your father in martial arts (so that your father can suffer a little without being seriously injured), so that he will know how insignificant his weight is.

Finally, explain to him that the coach's superb martial arts can only be relegated to the martial arts coach, so that your father can give up his gaudy posture and work hard.
