The meaning of "starting with love and stopping with etiquette" means:
It is okay to talk about love, but it cannot go beyond the boundaries of etiquette and law, that is, it cannot be illicit. The stop here It's not that we should stop feeling, but that we should stop within the scope allowed by etiquette and law, and we should not do things that go beyond etiquette and law just because of love.
Extended information:
This sentence comes from the "Book of Songs". It is said that the first chapter of the "Book of Songs" deleted by Confucius, "Guan Ju", describes a young man who longed for a woman. And the situation of not being able to sleep. Confucius' student Zi Fu wrote in his biography that "it is all about emotion but not about propriety and justice", which is what Confucius advocated, "pleasure without sexual immorality".
Confucius said in "Book of Changes: Xu Gua Zhuan": "There is heaven and earth, and then there are all things. There are all things, and then there are men and women. There are men and women, and then there are couples. There are couples, and then there are fathers and sons. There are fathers and sons. , then there are monarchs and ministers, then there are up and down, and then there are mistakes in the etiquette and justice." In the explanation of "Book of Rites", he also said: "Men and women eat and drink. The great desire exists."
Therefore, he revised the first chapter at the beginning of "The Book of Songs" and adopted "Guan Sui". Confucius did not mince words about men and women's eating and drinking, but emphasized that when men and women eat and drink, it is necessary to establish an ethical order of human relations.
