What are Gu Xiancheng's couplets? Thank you very much.

In reading, Gu Xiancheng praised the sages of past dynasties and tried to imitate the thoughts and actions of those respected people. He wrote a pair of couplets: "the sound of wind and rain, the sound of reading, the thoughts of family affairs, state affairs and the world", expressing his concern for society during his study. At that time, the social atmosphere was unhealthy, some people were immoral, had no concept of right and wrong, and paid attention to self-interest, have it both ways. Gu Xiancheng was outraged by this situation, and always wanted to find a way to correct it, combining book knowledge with social reality.
