Anger is very harmful, thinking is too harmful. God's heart is tired and easy to take, and qi is weak and disease comes to invade. Don't make it extremely sad and happy, eat well in the season. Three more nights of drunkenness, and the first one is morning anger. When sleeping in the sea, the sky drum rang and Ginkgo coughed up Yujin. Evil spirits are hard to invade, and essence comes from the whole body. If you want to stay away from all kinds of diseases, you should always be cautious. Calm nerves, be happy, cherish spirit, keep peace and save. Life is alive, and practice is in me. If we can follow this principle, flat land can be real.

Sun Simiao was a famous physician in the Tang Dynasty. When I was a teenager, I studied medicine because of illness and was familiar with hundreds of classics and history. He wrote immortal works, 30 volumes each, entitled "A Thousand Gold Farewells" and "A Thousand Gold Fang Yi", which occupied an important position in the medical history of China and was honored as the "King of Medicine" by later generations. Sun Simiao is not only skilled in medical skills, but also good at keeping in good health. He is over 0/00 years old and is the oldest doctor in China. On the Wang Yao Mountain in Sunjiayuan, Yaoxian County, Shaanxi Province, later generations left more than 100 stone tablets, one of which was engraved with Sun Simiao's "health inscription", which is the wisdom of health preservation.

Traditional Chinese medicine regards "essence, qi and spirit" as the "three treasures" of life, and holds that if a person wants to live a long and healthy life, he must "cherish qi" and "soothe the nerves" and pay attention to maintenance. Therefore, Sun Simiao first proposed that anger should not harm qi and thought should not harm spirit, so as to avoid the disorder of qi, disharmony of blood vessels and dysfunction of viscera, which would lead to various diseases. Sun Simiao paid special attention to mental health care, and thought that a person should keep a peaceful and optimistic attitude at ordinary times, try to avoid bad mental stimulation and excessive sadness and joy, so as to avoid the situation of "sadness can hurt the lungs" and "great joy and great sorrow". Sun Simiao also pointed out that maintaining a healthy lifestyle is an important aspect of health care. Therefore, life must be regular, pay attention to diet and keep a balanced diet. In particular, it is necessary to prevent eating and drinking at night, so as not to cause adverse consequences such as stopping eating, indigestion or stomach damage and liver injury. In living habits, we should pay attention to eating less irritating food and not partial eclipse. This is the meaning of "saving five flavors" in the health inscription. The so-called "Tiangu" means that you knock your teeth 36 times before going to bed (9~ 1 1 p.m.), and "Yinxing Yushujin" means that you wake up in the morning (3~5 a.m.) and stir your upper and lower palates for dozens of times, and you can swallow it with your mouth full. The above two methods are often mentioned in medical care books before the Tang Dynasty, which have the functions of preserving body fluid and fixing teeth. Sun Simiao believes that as long as everyone pays attention to health preservation, we can achieve the goal of "healthy qi is hidden inside, and evil can not be done", which can effectively prevent the body from being "not sick". Finally, Sun Simiao pointed out in the Book of Health Preservation that whether you can live a long and healthy life is actually in your own hands, and it is by no means destiny takes a hand. As long as personal health care is proper and health care is proper, you can live a long life.
