There are famous teachers in contemporary times, but there are still few masters. Master, absolutely not.
Tai Ji Chuan's masters died a lot in the past. Quite a few people died of fighting injuries in their early years. Some of them are even exhausted. For example, the old man Yang Chengpu of Zhao. There are many more. Look at some well-founded history books when you have time. For example, since the late Qing Dynasty, Taiji Chuan xxxx event.
He is a famous master of knee surgery in contemporary Tai Ji Chuan. In his later years, his legs and feet were not good, and he became a cripple. You'll know when you ask. There will be no roll call here. Actually, they're fine. It's just an exercise, which is understandable.
I'm not against the competition routine and the 24-style Tai Ji Chuan, but against the wrong way. As long as you practice correctly, everything will be fine. I practiced wrong. 1-3 months of leg injury may become a lifelong disease in 1 year. People think that Tai Ji Chuan doesn't practice well. I don't know. It's the teachers and students themselves.
In fact, other sports are the same. They are wrong in practice, or they are forced to practice injuries because of stress. Almost every sport has it. Is not unique to Tai Ji Chuan. Such as running, swimming, basketball, football, badminton, cycling, skating,,,
We ordinary people just attract their advantages and avoid their shortcomings.
