Translation: There are sorrows and joys in life, reunions and partings, the moon will be full and it will be missing. Such things never happen. It is a regret that can never be changed from ancient times to the present! 2. If the world is unhappy, it will always be seven or eight.

The quote comes from the "Book of Jin·Yang Hu Biography": "Huiqin and Liang were defeated repeatedly, and Hu Fubiao said: 'Wu Ping, then Hu will decide on his own, but he should quickly help the great merits.' There are many different opinions. Hu sighed and said: "The world is not going as you wish, and it is always seven or eight, so there must be no end." "Nine", and "you can talk to people about the same thing" was added, and the meaning changed, indicating that there are many unsatisfactory things, but there are not many things that can be talked about with others. It's hard to describe. 3. Sweet melons have bitter stems, and jujubes have thorns.

"Sweet melons have bitter stems, and jujubes have thorns" uses a bixing technique, which means that no matter how sweet the melon is, its location All the melon stems are bitter; no matter how delicious the dates are, they all grow on thorny thorns. Philosophically speaking, nothing is perfect in the world. It is incomplete to regard something as perfect because of its advantages, and it is also incomplete to regard something as useless because of its shortcomings. 4. Gold has no color, and white jade has slight flaws.

Source: "Ji Xing" written by Dai Fushi of Song Dynasty.

Translated as: There is no perfect red gold, and there is no completely flawless white jade. 5. No gold is pure, and no man is perfect.

From Song Dynasty Dai Fuzhu's "Reporting on Xing": "Gold has no color, and white jade has slight flaws. Asking for help but not for preparation, I wish to live in Laojun's home."

It is also a metaphor. You cannot require a person to have no shortcomings or mistakes. There is no perfect person in the world, and no gold is perfect. People have strengths and weaknesses.
