In Taiji push hand, when I push your arm, I will expect 2 responds.Wing chun sticking hand training doesn't have a plan, it has a process. A step by step process.
1. Resist - When you try to use your force to against my force, I can borrow your force, change my push into a pull.
1. Yield - When you try to yield into my force, I can also borrow your force, change my push into more push.
The WC sticky hand may not function like the Taiji PH. You try to give your opponent limit amount of options. Whatever the option that your opponent may take, you have some follow up waiting for him.
