Rivers and lakes are neither rivers nor lakes. The reason why rivers and lakes are rivers and lakes is because there are always people living next to the water. People are the world, and people's hearts are the world. In this kind of rivers and lakes, one can cut off the water with a sword and enjoy the grudges, or one can drink wine with Han Shu and Qin Yun make the river. It can be busy and even bloody, or it can be warm and elegant. Yeah? No? The sword is not in the hand, the sword is only in the heart. --The plot is fictitious, please do not imitate it.
