Du Daosheng (former professor of Sichuan Normal University) was born in 19 12, and 1937 graduated from the Chinese Department of Peking University. He studied Chinese characters with masters of Chinese studies such as Qian Mu and Hu Shi, and took Chinese characters as his lifelong research object. Through the study of Chinese characters, Mr Du Lao discovered the roots of China traditional culture. He took China traditional culture based on Chinese characters as his foundation and called it a "walking dictionary".

That day, I asked Du Lao for advice on health preservation, and the old man casually replied: Reading and teaching. Furthermore, what books have you read for so many years? The old man said that it was mainly "Shuo Wen Jie Zi". Du Lao's eyes lit up when he talked about the love of his life. "There are more than 8,000 Chinese characters in China, but actually there are only more than 5,000, some of which are variants and tautology, and there are more than 3,000 commonly used words. There are more than 500,000 words in the annotation of Shuo Wen Jie Zi, involving countless classics, and one person can never finish reading it. "

Twice rated as a healthy old man.

Du Lao, who won the title of "Healthy Old People in Chengdu" at the age of 85, won this honor for the second time at the age of 90. He is now 95 years old, in good health and taking care of himself. Reading and teaching is indeed the best spiritual food in his life. From 1937, Peking University returned to Sichuan to start teaching, and has been teaching for more than 50 years. This kind of free, self-cultivation life is of course of great benefit to people's health and longevity. But as students, we know much more about Du Lao and his longevity. "A dish, a gourd ladle of wine, in this base lane. If you can't bear it, you will be worried. If you go back, you won't change your fun. Xian zai, you come back! " Confucius' praise for his disciples is really appropriate for Du Lao. When we were at school, Du Lao lived in a room less than 20 square meters on the second floor of the office building of the Chinese Department of Sichuan Normal University. This house has a bedroom, a kitchen and a study. The bathroom is still downstairs. Thirty years later, it's still the same, but there are too many things piled up, and the room looks more shabby and dirty. Du Lao usually eats in the canteen. In the morning, he has porridge, steamed bread and pickles (his favorite bean curd), a meat at noon and a meat at night. In general, you should drink 125 yuan's soju in the evening (he doesn't pay attention to whether it's famous wine or not, but it must be brewed from grain. Sometimes at noon, but there must be restrictions). In recent years, his legs and feet are inconvenient, and his family asked someone to take care of him, but he refused. He said, "If someone takes care of me, I will become lazy and lose my ability to take care of myself."

This is my understanding of Du Lao's health preservation. This reminds me of Montaigne's "principle of life": obey fate and give yourself to it anyway. Being content with fate is also a survival wit-95-year-old Du Lao seems to know this well.
