Introduction to the second spring in the world: The second spring in the world is located at the east foot of Huishan Mountain, formerly known as Huishan Spring. Lu Yu, the tea sage of the Tang Dynasty, once visited friends in Wuxi and stayed at Huishan Temple. He admired the scenery of Huishan with "deep springs and thick green trees". After drinking from Huishan Spring, he fell in love with the clear and sweet spring water. Later, Lu Yu rated the water in the world as the 20th grade, and Huishan Spring ranked second, so the reputation of the second spring in the world came into being.
