It will rain. What do you mean, mom wants to get married?
It's going to rain, and mom is getting married; It's going to rain. It's time for mom to get married.
Its profound meaning is: what is bound to happen is unstoppable; The development of things has its objective laws and does not depend on human will.
It is natural and humane for girls to get married, which is the inevitable law of human society; And "it will rain" is an inevitable law of nature. It is based on this logical similarity that the sentence "It's going to rain, and my mother is going to marry" has a strong vitality and has been passed down to this day.
Originally, this sentence was intended to express a kind of "respect for heaven and know life", that is, it is an act of God that is irreversible.
Wang Youguang of A Qing wrote in Volume II of Wulian that "it will rain, and the mother will marry": "Heaven, pure yang has no yin, and if it rains, she wants to seek yin from the yang; Mother, lonely in yin and without yang, wants to get married, and seeks yang in yin. If the arrow goes away, it will rot like marrow, its reason is like this, and its environment is like this. " This passage explains the "truth" of "it will rain and mother will marry" from the perspective of yin and yang.
Judging from this article's explanation of "Niang, lonely and without yang", it is obvious that he regards "Niang" as an unmarried woman. If you are a married "mother", you can't say "lonely yin without yang"
