This is a Sichuan folk proverb.
The original text is poor and weak, but rich and proud. If you have money, you should remember the days when you have no money. Don't forget when you are frustrated. There are many friends with wine and meat. How many people have you met when you are in trouble? People come to beg me for three spring rains, and I beg them for June frost!
It shows that poor people and people in need speak weakly, and rich people and arrogant people are beaten to death even if they hum their noses; When you have money, remember the hardships when you have no money, and don't get carried away; When I was rich, I had many fair-weather friends. How many friends did I meet in trouble? I tried my best to help others when they asked me, but when I needed help, no one helped me.
The source is a sentence from an augmented sage. Zengguang Xianwen is an enlightening bibliography of ancient children in China. Also known as "ancient sages" and "ancient and modern sages". The title of the book was first seen in the drama Peony Pavilion in the Wanli period of Ming Dynasty, so it can be inferred that this book was written in the Wanli period at the latest. Later, it was changed to this appearance after the continuous supplement of the literati in the Ming and Qing Dynasties. It was called "adding glory to the text" in history, commonly known as "adding glory to the text". I haven't seen any books, except that it was revised by Confucian scholars during Tongzhi period in Qing Dynasty, which is probably the crystallization of folk creation.
