He used to be the president of Gansu Provincial Hospital of Traditional Chinese Medicine and the president of Gansu Provincial Acupuncture Society. Famous acupuncture expert and chief physician, known as "Long Yuan Shenzhen". Eighty-year-old Zhang is handsome, quick-thinking, observant and steady. So far, he still insists on teaching and educating people, treating diseases and saving lives. Zhang Lao has suffered from several serious illnesses and three surgical injuries, but his body and mind are still healthy. Zhang Lao pays attention to recuperating the mind, exercising limbs, living a regular life, preventing diseases, and controlling diet. His health preservation methods are worth learning. First, adjust the mentality and maintain righteousness. People live in nature and are influenced by natural environment and social factors. The stimulation of external factors can lead to changes of seven emotions and diseases. People can't be isolated from the world. The key is how to treat the influence of external environment on people correctly. I think that only by paying attention to psychological adjustment can we maintain normal and coordinated physiological activities of the human body, which is an important link in health care. Therefore, maintaining psychological balance and mental optimism, controlling the seven emotions of joy, anger, worry, thinking, sadness, fear and shock, getting rid of abnormal desires and fame and fortune thoughts, and filling the internal defense with true qi can reduce diseases. Don't get angry when you encounter difficulties, but laugh often, which is very beneficial to your physical and mental health. I have a bad temper and get angry easily about things I don't like, but I take more measures to save my anger so as not to hurt my liver. In order to make the past sadness indifferent, I plan to do Taiji Qigong in the morning and evening to keep my abdomen, get rid of other thoughts, keep my mind calm and enliven my memory. Watch TV, listen to the radio, enjoy music, Beijing opera, etc. After tea, to eliminate mental tension and dispel melancholy. Second, exercise limbs and dredge bones and muscles. I have been thin and sick since I was a child. /kloc-studied medicine at the age of 0/4,/kloc-practiced qigong and boxing at the age of 0/7. Later, due to physical weakness, according to the teacher's instructions, in addition to insisting on practicing Qigong, I mainly practiced Tai Ji Chuan and Taiji Sword. In order to maintain his skill, he practiced Qigong, Tai Ji Chuan and Taiji sword for half an hour 1 hour in the morning and evening. This is the reason why I live long. Exercise health care means regular exercise, but perseverance, exercise and restraint. My motto for medical care is to keep healthy, live long and be happy. Besides exercising in the morning and evening, I often go out for activities, such as shopping and taking a walk after dinner. Even when I am sick or dizzy after operation and can't do outdoor activities, I use qigong, do indoor activities and massage my abdomen with my hands to promote gastrointestinal activities and help digestion, absorption and excretion of food. Third, eat moderately and live regularly. I eat three meals a day regularly, drink when I am hungry, eat slowly and taste the food carefully. Don't get angry before meals, talk less during meals, don't overeat and indulge your stomach. Drinking tea is my hobby. I like jasmine tea. I think drinking tea in the morning can refresh my mind, and drinking tea after meals can remove greasy and help digestion. I object to the bad habit of lying down after meals. Rinse your mouth, take a walk and massage your abdomen with your hands after eating. Fourth, disease-free prevention, early treatment of diseases I advocate not forgetting the danger, treating diseases first, and treating diseases early. Newborn ailments should be treated in time, and there should be no luck. Once a serious illness occurs, it is necessary to actively treat it and establish confidence in overcoming it. Don't always worry about the past, for fear will increase your mental burden and aggravate your illness. Early treatment of diseases should be combined with drugs, and it is forbidden to use drugs without diseases, treat minor illnesses and abuse tonics. I don't get sick every day. As long as I pay attention to health care, I don't need to use drugs indiscriminately. Five, abstinence from sex and prolonging life, excessive sexual desire is the great precept of health care. Only by abstaining from outbreeding can we preserve the essence, strengthen the kidney and be beneficial to health and longevity. Abstinence is not living alone against physical needs. Husband and wife love each other, live in harmony, take care of each other, have fewer children and have good children, which is conducive to physical and mental health. Old people are widowed, life is inconvenient and lonely, so it is necessary to remarry, which is not only conducive to spiritual sustenance, but also to health and longevity.
