I thought Tang Xue Hua (he has the same initial as The Other TXH!) was mainly a WS coach. he was training Gong Zhi Chao, etc. while Hou Jiachang was the MS coach.
Well - we do need to see more variety of players winning SS tournaments, right? So it is essential for us to do our part ....... wakakaakaka.
Hou Jiachang was the coach of Zhao Jinhua for sure. I talked to him before and he gave me his book which has all the details!
