Introduction to Yinma Pond: Baima Stream was the horse breeding farm of King Wu during the Spring and Autumn Period. King Wu’s precious horse, Red Rabbit, was grazed here on weekdays. According to legend, King Helu of Wu led thousands of troops to attack the country of Yue. When the people were trapped and the horses were exhausted, the horses drank water one by one and stepped on the big rocks under the soil with their horseshoes, forming a horseshoe-shaped stone pond, which is the site of the horse drinking pool.
