Generally speaking, there are two forms: static and dynamic.
The main function of exercise is to complete the corresponding functions through the activities of limbs, and the rest is generally done through silence.
The dynamic and traditional ones are Yijinjing, Six-character Tactics, Baduanjin, Wuqinxi, Twelve Piles in Emei, Wild Goose Qigong and so on.
There are many static ones, but basically they are nothing more than regulating breathing, observing points, supervising the environment and visualizing.
As for the more formal method you said, it is actually very simple:
1. Quiet and natural
Adjust interest rate
Focus on cavitation
4. Taoism is natural
The so-called real word is the first word, fake thousands of books. That's the truth. According to the above method, it is easy to tell whether static kung fu is formal or not.
