It first appeared in the version of "People in Jianghu" 1979, when the wife of director Dong, who was in Jianghu at that time, participated in the screenwriter and quoted this sentence. Later, because Bai Yutang, played by Andy (22 minutes in the fifth episode and 0 minutes in the tenth episode of "Ten Years of Lights on a Rainy Night in Rivers and Lakes" in 2007), said this sentence too much, and it was widely quoted by netizens and became an online buzzword.
The general meaning of this sentence is: people living in the world should have a temperature in their hearts, be measured in doing things, and have morality. For friends, three points are sincere and seven points are tolerant. Be very tolerant of your family. Be moral, thoughtful, tolerant and patient, don't treat people with things, don't be mean, and be kind to others and you will feel at ease all your life.
Life goes by in a flash. If you have a bad personality, you will be lonely even for a short time, because no one will like a person with a bad personality. Many things are not measured by money. Personality is gradually accumulated, so more people will be willing to be friends with you, otherwise others will only stay away from you.
