It's so funny that when talking about "how to enhance Taiji PH", Windwalker then says that some people may train Taiji PH for health. The moment that combat and health start to mixing in one discussion, further discussion won't make any sense.#1 is good to know if someone gets past #2.
One time a girl added "lotus hands" into her Taiji form. I asked her why. She said, "It looks pretty." I then knew any further discussion with her could be meaningless.
