Introduction to Shuizhen: Built in the Yongle period of the Ming Dynasty (1403-1423 AD), it has a history of more than 500 years and a total length of more than 1,200 meters. After leaving Nanhu Lake, it irrigates farmland and fruit trees, and then flows into Suixi River again, nourishing the whole village with coolness. It can be said to be the "tap water" of ancient villages.
