I haven't heard of it. Sometimes what you see is not necessarily true, let alone what you hear from hearsay. You'd better not talk nonsense.

However, I still have something to say about the Dojo. More than ten years ago, I worked as a culture teacher in a martial arts school in our town. The martial arts school is privately booked, and the Education Bureau has no record. They are all boarders, and most of them are students who don't like studying in ordinary schools. Therefore, under the background of rebellious hormones in youth, many students are rebellious, bloody, aggressive and sensitive. In this way, there will be many rules in the martial arts school. In my impression, a boy broke the rules and was beaten by the curator with a stick for three days and could not get out of bed. Since then, boys have changed a lot and entered many schools.

Many times, I think that punishment is not an end, and people should learn to be kind.
