The middle cold spring among the six famous springs.

Located in the west of Jinshan Temple in Zhenjiang, Jiangsu Province, at the foot of Shidan Mountain, it is known as the first spring in the world. Liu Ren, the minister of the Tang Dynasty, was a famous spring. According to the two standards of water quality (clear, lively and light) and water taste (sweet and bitter), he was named "the six famous springs in the world" and the middle cold spring was listed as "the first spring in the world". There is a pavilion in the south and a building in the north, surrounded by stone fences. The stone fence is engraved with the four characters of "the first spring in the world" written by Wang Renkan, a calligrapher in Qing Dynasty.
