Longteng Martial Arts Hall: It's very strict. It's a bit of a scam.

The seventh floor of Baihua is "extremely advanced": relatively practical, I heard.

Children's activity center "Hengfu": the upgrade is faster. I study here. The technology may not be very good, but it is enough. In a summer vacation (3 months), I can change from a leucorrhea to a black belt.

It usually takes about 2 hours.

It seems that the children's activity center is only 100 (phase I)
