A simple sentence: read the classics intensively, be diligent and dedicated.

The details are as follows:

Fan Zhongyan studied hard for years, from spring to summer, through autumn and winter; he danced with a sword in the early morning and slept in his clothes in the middle of the night. Others look at flowers and the moon, but he only seeks pleasure in the Six Classics. A few years later, Fan Zhongyan had a thorough understanding of the main themes of Confucian classics such as The Book of Songs, The Book of Documents, The Book of Changes, The Book of Rites, and the Spring and Autumn Annals. own responsibility.

Fan Zhongyan has been studying very hard since he was a child. The Zhu family is a wealthy family in Changshan, but for inspiration, he often goes to the nearby Liquan Temple in Changbai Mountain to stay and study, morning and evening. Then he read the satire and recited it, which left a deep impression on the monk: At that time, his life was extremely difficult. He only cooked one pot of thick porridge every day. Mix with vinegar sauce, finish eating and continue reading. Later generations had the reputation of being a man who had no time to live, but he didn't mind this kind of poor life, and spent all his energy looking for his own pleasure in books.

Fan Zhongyan cherished the new learning environment very much and studied day and night. One of Fan Zhongyan's classmates and the son of Nanjing Liushou (the highest official in Nanjing) saw that Fan Zhongyan was eating porridge all year round, so he gave him some delicious food. He didn't even taste it and allowed the food to get moldy. It wasn't until people began to blame him that he bowed his head and thanked him and said: "I have settled down to a life of eating porridge. Once I enjoy a good meal, I am afraid that I will not be able to eat bitterly in the future." Fan Zhongyan's difficult life is a bit like Confucius's wise disciple Yan Hui; a bowl of With rice and a ladle of water, in a back alley, others complained endlessly, but Yan Hui did not change his joy.
