It's not a class thing at all There are several old people in China who are invited to teach martial arts in Japan several times every year. They practice everything. How do they compete? Although there is no difference between kung fu and karate, on the technical level, the contrast between fine Tai Chi and rough karate is clear at a glance. It takes time to grind things that are too fine, and the understanding requirements for practitioners will be much higher than those for crude karate. Therefore, few people succeed in martial arts. 2. When you meet someone, the coach doesn't understand and you haven't really been taught. 3. I'm not very savvy. 4. Although the understanding is relatively high and the teachers I meet are better, I am eager for quick success and short-sighted.
