Well, the crazy thing about Tai Chi, I'll give you a little information about it that you may or may not know, but the idea with Tai Chi is that if you master it or you have that control over it, you should be able to move 1,000 pounds with just four ounces of energy. So, the idea of them pushing constantly means if something ever came to them, They push that aside without even thinking about it. Because just four ounces of energy can divert. It's almost like tripping a giant.
