Chi sau is not fighting. Chi sau is to learn and train:
- How to use your energy when necessary
- Develop sensitivity. and reflexes
- Train to have good position
- Good hand techniques.
Even a 90 years old can still chi sau ,that is because he understand the above theory. I have seen Grandmaster Ip Chun chi Sau with a French Chef 280 Ibs and he tried everything to hit him. He could not touch him. That was at 73. I have never seen anyone move as fast as Grandmaster Ip Chun and Ip Ching (80 years old ). Grandmaster Ip Ching is a re known fighter. I witnessed him sparring with a Karate Champion in Manchester in 1994. Awesome power and reflexes!
