Martial art schools (Tianjin)

Hello folks,
I am on the grand tour of China (lol) searching for a martial art school (wing chun specifically). I am on my way to Foshan at the moment, planning to visit Gulin and Shandong area. If any of you have some advice for the best places to look for martial art schools, please post. I am interested in private authentic experiences rather than large commercial schools.
Any info will be greatly appreciated,
Thank you all,
Zhenya
