Introduction to Songjing: Songjing is located on the southeast beach of Aoqian Village, Yun'ao Town. It is said that it was dug by Zhao Shi, the Emperor of the Southern Song Dynasty who was forced to evacuate Lin'an by the Yuan soldiers at the end of the Southern Song Dynasty. There are three wells, one of which is the Dragon Well, dedicated to the emperor. For drinking; one is Hujing, for ministers to drink; the other is Majing, for entourage and soldiers to drink. Later generations also called the three wells Songjing. Over time, the ancient wells were buried by tides and sand, and only appeared occasionally when typhoons passed by. In order to prevent them from being buried again, the locals surrounded the "horse wells" that appeared in previous years with guardrails. This is what we see now as the "Song Well" well".
