The water margin in the Water Margin no longer exists. Liangshan Park is located in the west of Shandong Province. According to historical records, Liangshan Park in Northern Song Dynasty was a vast lake. However, nowadays, the water margin in Shandong has become a densely populated area with endless farmland. The only thing left is an isolated stone pier on the plain, which seems to be telling the past history. The growth and extinction of a lake is closely related to its surrounding climate, hydrology, geology, landforms, vegetation and other factors. We should cherish and protect these "eyes of the earth".
