Despite having to pay 600NT, he was pretty good. He wanted you to NOT have to come back soon, so that's a good sign that he isn't seeing you just for the money.
It wasn't an instant cure, but he did tell me that my two legs were imbalanced, which led to my injury. He did put me on a few machines that twisted and pulled me to "straighten" me up and also taught me how to fix the issue on my own.
Worth a try, but like I said, not an instant cure. My parents went multiple times and said that an appointment is a must!
P.S. going to have to work up your mandarin skills bc the guy doesn't speak English!
