The ancients thought that many shallow rivers could only cross the border by raft, but not by boat, because the water was too weak to carry ships, so such rivers were called weak water. Therefore, many weak waters with the same name but different rivers are recorded in ancient books such as Shan Hai Jing and Ten Kingdoms. There is water in the north of Kunlun Mountain, which is recorded in Shanhaijing, but it can't beat mustard seed. That's what weak water means Some appellations are still in use today, such as a weak river on the map of Gansu Province. Weak water is also used to refer to the Poyi River or Heishui River in the northwest, and of course it is limited to specific geographical works.

In later ancient literature, weak water was gradually used to refer to dangerous and distant rivers. There is a famous saying in Su Shi's "Jinshan Miaogaotai": Penglai is unreachable and Wan Li is weak. It can be said that this is the first time that weak water has used specific figures. There is also a saying in Zhang Xiaoxiang's Song Dynasty's Poem "Looking at Jiuhua Mountain":' There is no weak water at the beginning when you look at Penglai. Weak sentences are rare in other poems, but they are used more in later novels.

Sister Bao doesn't like you How are you? Sister Bao was good to you the day before yesterday, but now she is not good to you. How are you? Hello today, but not after. How are you? You are good to him, but he is not good to you. How are you if you don't get along with him, he insists on getting along with you. How are you? " Baoyu stayed for a long time, then suddenly smiled and said, "I'll just get a scoop of water." Daiyu asked, "What should I do if the ladle floats in the water?" Baoyu said, "If you don't float in the water, the water will float." Daiyu said, "What can we do if the water stops the pearl from sinking?" Baoyu said, "The Zen mind has been stained with mud, so I won't dance partridge spring breeze." Daiyu said, "The first precept of Zen is not to curse." Baoyu said, "It's like three treasures."
