Introduction to the Sanqing Hall: Next to the ginkgo tree stands the Sanqing Pavilion. It was built in 510 BC. Due to historical reasons, only the ruins remain. A new Sanqing Hall was built behind the ruins, which enshrines the Taiqing Daode Tianzun, Yuqing Yuanshi Tianzun and Shangqing Lingbao Tianzun.
