Ambergris Spring Introduction: Ambergris Spring is a natural stone spring. Its name comes from a historical legend. In the third year of Wude in the Tang Dynasty, King Li Shimin of Qin and Song Jingang fought and confronted each other. They stationed troops at the head of the tower and were trapped by lack of water. . Suddenly, I saw the clouds and mist steaming in Longji Ridge, and I could vaguely see a divine dragon spitting holy water from its mouth. Suddenly the spring water gurgled and formed a waterfall shaped like a dragon's whiskers. Li Shimin was overjoyed and named them Ambergris Fountain and Longxu Waterfall. Later, Li Shimin went to Mianshan to thank the rain and built the Xie'en Square and Xie'en Pavilion to express his gratitude to the dragon for giving water.
