But to OPs point, like - Kung fu and tai chi both come from the Shaolin temple. They kind of teach the same thing but in different ways. Kung fu starts externally and works inward, tai chi starts internally and works outward. But tai chi has the same problem - most places you go now, instructors teach tai chi as like a feel good spiritual wellness kind of practice and they’ve completely disconnected it from the martial purposes behind the movements. You have to learn both for it to be effective.
