Taekwondo adult class training, fight real combat, the result of a trainee was injured, the responsibility should be who is responsible.

The reasons are as follows:

1. The instructor has declared not to fight without protective gear.

Secondly, Taekwondo is inherently bumpy. Before signing up students should be mentally prepared, plus it's an adult class.

To fight the actual battle would have been unavoidable, or he himself hard on, I think if the taekwondo hall is responsible for, that can be directly closed. There would be no need to practice in the future.

But if the instructor who was a temporary guest student can't provide credentials as a student of the dojo, then he should be responsible.
