Introduction to the Ancestral Temple: The Ancestral Temple was built in the Yuanfeng period of the Northern Song Dynasty (1078~1085). At that time, the Pearl River Delta region was mostly a water town with many floods, and Beidi was the legendary god of water control, so Beidi was regarded as the god of flood control. The patron saint of Chancheng people was enshrined. But in the Ming Dynasty, the ancestral temple was destroyed. In the fifth year of Hongwu in the Ming Dynasty (1372), the ancestral temple was rebuilt.
