This is a self-encouragement couplet compiled by Xie Zixiu, the grandfather of Bing Xin (Xie Wanying), a poet, novelist and essayist, and serves as a family motto for educating future generations. The "content" of Lao Zi, the language version of Part I, means to be satisfied with material enjoyment, fame and status, but not greedy. Contentment will not be humiliated. It not only contains the idea of "preserving our health by being wise", but also contains a reasonable core to restrain the indiscriminate desires and maintain the harmony between body and mind. "If you don't know enough" means "Learn from the Book of Rites": "Learn and then know enough, … know enough, and then you can be self-defeating." The general idea is that only by studying can we understand our own shortcomings and know our own shortcomings, and then we can study hard in turn. "Lack of knowledge" shows positive enterprising spirit, strong desire for knowledge and modest and studious attitude. Keep making progress in learning and career, and never be satisfied.

The "promising" in the bottom line refers to doing something. The text Book of Rites: "Love him till he dies, and raise him for something." That is to say, cherish life in order to wait for the opportunity to play a role; Maintaining the body is to hope to make a difference. This is the Confucian attitude of actively using the world. "Doing something" means resolutely not doing anything that does not conform to justice and morality. The text "Mencius under Li Lou": "People can do something if they don't, and then they can do something." The general idea is that people can only do something if they don't do something. The second part puts forward the boundary between doing something and doing something: that is, doing good deeds and things that benefit the country and the people should be actively done; We must persist in doing wrong things, evil things, and things that harm others and benefit ourselves. Xu Teli, a proletarian revolutionist and educator in China, wrote a gift couplet to several young shop assistants on "Doing something and doing something for others": "It is useless to read the books about your family often." It points out the direction for people to cultivate their self-cultivation.

Bing Xin once made a unique interpretation of his grandfather's family training couplet: be content with some things, such as life; You can never be satisfied with some things, such as study and career; Some things must be done, while others must not be done. She always hangs this couplet in her study to show her obedience to her ancestors' instructions.
