Stone Beasts in the River by Ji Yun, a writer in Qing Dynasty.

Excerpt from the original:

If a stone is thrown into the river, you should look for the upper class. The cover stone is solid and heavy, the sand is loose and floating, and the water can't wash the stone. Its counterattack force must be to bite the sand as a pit under the stone. Gradually excited, deep, until the stone is half, throw the stone into the pit. If you take another bite, the stone will turn again. Turn around and I'll go back and forth.

Translation:

Stones fall into every river, so we should look for them from the upstream. The nature of stone is hard and heavy, and the nature of sand is loose and light. Water can't wash away stones. Its reaction force will inevitably form a pit under the stone and directly impact the sand in front of the stone. The deeper the rush, the halfway through, the stone must fall into the hole. Hit it like this and the stone will move again. Keep going, so don't go upstream.

Creation background

In his later years, from the fifty-fourth year of Qianlong (1789) to the third year of Jiaqing (1798), Ji Yun began to collect folk stories about foxes and ghosts, including many texts about textual research, and compiled the Notes of Yuewei Caotang. This article is one of them.

The main content of The Stone Beast in the River is that the stone beast falls into the river. Because of the impact of water and the weight of the stone beast itself, it is necessary to look for it from the upstream where the stone beast fell.

The article means that when considering a problem, we should analyze the reasons from the outside to the inside and get the correct solution. Many natural phenomena often have complicated reasons, so we can't just know one without knowing the other, and we can only make subjective judgments based on common sense.

It is necessary to correctly analyze and comprehensively consider, like the old river soldiers in this paper, not only to consider the proportion of stone animals, but also to correctly analyze the interaction between water and stone animals, and then to analyze the local changes of riverbed morphology caused by recoil caused by this interaction. Only in this way can we come to the correct conclusion.
