Fan Zhongyan's family is poor. When he was studying in Du Nan College, he always cooked two liters of rice and cooked a pot of porridge. After a night of solidification, he cut it into four pieces with a knife, eating two pieces in the morning, two pieces in the evening and some pickles. A son stayed to study with him, and he wanted to go back to his hometown to accompany his father. Before he left, he cooked several good dishes for Fan Zhongyan. Fan Zhongyan put it aside, and soon all the food was rotten. The son left behind said, "My Lord heard that you live a light and poor life and sent these foods. Why don't you eat them? " Fan Zhongyan said, "It's not that I don't thank you for your kindness. It's just that I have been eating porridge for a long time and my heart is very stable. Now I want to enjoy such a sumptuous meal. How can I eat this bowl of porridge again? "
