This sentence comes from Zhu Bailu's "Zhu Zi Jia Xun" in the late Ming and early Qing Dynasties:
Don't forget to give help, but don't forget to accept it. Leave room for everything and be proud of it.
People are happy, not jealous; People should not be happy when they are in trouble.
Vernacular translation:
Don't take your kindness to others to heart, but always take your kindness to others to heart. No matter what you do, you should leave room; If you are satisfied, you should be satisfied, and you should not go any further. Don't be jealous when others have festive events; Don't gloat when others are in trouble.
Extended data:
The idea of "never forgetting benevolence and righteousness" has a long history in China. As early as the Warring States period, Tang Ju once said in lobbying Xinlingjun: "People are virtuous to me, and we must not forget it; I am virtuous to others, and I can't forget it. " I should not forget others' kindness to me, but I should not always take it to heart. )
Tang Ju said to the new Ling Jun, "I heard that there are some things you can't know, some things you must know, some things you can't forget, and some things you can't forget." Xin Lingjun asked, "What does this mean? "
Tang Ju replied: "I need to know that people hate me; I hate others, but I shouldn't let him know. I should not forget others' kindness to me, but I should not always take it to heart. Now you have killed, saved Han, broken and saved Zhao, which is a great kindness. Now Zhao Wang personally comes to the suburbs to meet you. I hope you can forget your greatness! "
New Ling Jun replied, "I will certainly remember your advice."
Both Zhu and Tang Ju warned people to always be grateful and help others.
