Finding My Roots - Tang Ancestral Hall

Last Saturday I went to help out at an event similar to Amazing Race, and was assigned to Pit Stop 3 - Tang Ancestral Hall in Ping Shan, Yuen Long. It was completely by chance my last name is Tang, so I joked about finding my roots there. Coincidentally, there was a middle-aged, retired cop walking around the hall at night, so I chatted him up and he started telling me the history of the Tang's. By the way, in that village, most residents have the last name, Tang.
