My son Fu Heng was born in 1929. When New China was founded, he was admitted to the Chemistry Department of Peking University. After graduating from university, he was assigned to the Institute of Petroleum Chemistry, China Academy of Sciences, and engaged in structural chemistry research for more than 40 years. He is one of the pioneers and leaders in the study of single crystal structure in China.

In his early years, Fu borrowed twenty taels of silver because he was far away from his hometown and spent a lot of money. Father didn't blame him when he got home during the winter vacation. Just take him to the Yellow River, tell him to take off his shoes and socks, jump into the water together and say to him, "That's how I earned my money." Fu felt guilty and advocated simplicity all his life. He is called "General in Cloth".
