The first time I came across this sentence was Liang Yusheng's "Seven Swords Down the Tianshan Mountain", which expresses the highest realm that people pursue in the world of Jianghu. Jianghu is a family, and it doesn't matter where you are in life.

The original text is from "Zhuangzi": "When the spring dries up, the fish and the fish are on the land. It is better to forget each other in the rivers and lakes." It is also a state of expression, but there are differences. : Most people hope to stay with their loved ones day and night and enjoy each other's daily lives. And forgetting each other in the world, that means, let us treasure the beauty of the past in our hearts and write a new life each. We know that we love each other, but we know better that making our lives more exciting is the best return for his love and the best way to love him. It's just that this state of mind is too free and easy, and not for people like us to accept it.
