In martial arts, the biggest enemy is self. Inside you struggle because you want to prove something.

Martial arts have two parts. One is external, other internal. The external is physical part. The internal is philosophy of how to be, what kind of person learns martial arts.

But recently I've, the past few years, I'm more focused on meditation. It's not a physical part. It's more mental part, to understand life.

One cannot choose how one's life begins but one can choose to face the end with courage

Zhang is a friend of mine: he said forget about acting and just do normal things in the movie.

I stepped into the martial arts movie market when I was only 16.

Usually action films have a formula: good guy gets in trouble, his wife dies, friends have problems, so he goes to the mountain, learns martial arts, comes back, and kills the bad guy.
