At present, health care is a very popular topic. A wide variety of health care doctrines and health care programs and books are flooding the market. However, with such a wide variety of health food and fancy health care methods, and so many believers blindly believing in these methods, the results are not as good as they should be, and many people still suffer from illness and premature aging. I am still young, talk about health care should be the patent of the old Chinese medicine, but whenever I see patients struggling with pain, my heart is really intolerant, reluctantly for the health of their own views, please forgive me if there are omissions and bias. In summary, the long-lived elderly, their means of health vary, some daily food some special food to live a long life (such as wolfberry, five grains of porridge, Shou Wu, Panax notoginseng, etc.), some what health care products do not eat just a light meal also live a long life; some daily diligent exercise to live a long life, some day meditation can also live a long life. The means of health care are different, and some means are diametrically opposed, why can they achieve the purpose of health care and longevity? Many people imitate the same means of health care, but why do only a few people live longer? Chinese medicine is about treating illnesses and seeking the root, so should we seek the root of health care. This is like the root of a big tree, and the end is the branches and leaves of the tree, only this strong will have the end of the prosperity, so health care must find all the common features of the long-lived elderly, rather than their different habits of life, these last parts. They love their bodies and love life, and because they love themselves, their surroundings are full of love, and they will pass this love to everyone around them invisibly, so there is not a long-lived old man who is not loving. Because of love, they will choose some ways to benefit their bodies, and there are many of them, eating or not eating health food, exercising or not exercising, all the means of health care will only work if they love themselves. If you are full of hatred and have no care for your body, it will be difficult for you to live a long life even if the gods are alive. This kind of love is not selfish; one can only love others if one loves oneself. As Confucianism says, “Cultivate one’s moral character, cultivate one’s family, rule one’s country, and level the world.” Only by doing well for oneself can one better help others. If a person hates himself but shows love for others, he must be a hypocrite. If you love yourself and give this love to everyone around you, you are a selfless person; if you love yourself but deprive the love of others around you, you are a selfish person. With love on your side, then you must love your body everywhere and must not let it be damaged, which requires attention in daily life to avoid damage. The story of Butcher dismantling the cow is recorded in “Zhuangzi – Master of Health”, and Wen Hui Jun understands the way of health by appreciating the process of Butcher dismantling the cow. The knife used by the Butcher to cut thousands of hard and strong cows, the blade of the knife was not damaged for 19 years, just because his knife followed the grain of the cows. We live between heaven and earth, and in order to keep our bodies from being destroyed by heaven and earth, we must follow the grain of heaven and earth and not fight against it. Nowadays, many people tend to be proud of their achievements in overcoming nature in a short period of time, but they do not know that a short period of victory will lead to a complete defeat in the end. Only harmony can be undamaged, and with love in our hearts, we can do things in harmony with nature. In fact, the Yellow Emperor’s Classic of Internal Medicine explains it thoroughly in just eight words: “Tranquility and emptiness, true qi follows”. This is the fundamental law of health care from ancient times to the present. The so-called calm and empty, is the heart to maintain the feeling of being light sweet water nourished, this feeling is not the feeling of winning the lottery, promotion, but as the sweet feeling in the heart after helping others, that is, the feeling of love. Nourishing your heart is important, a bad state of mind is like poisonous grass, long-term in it, will make the body’s ability to resist disease is reduced, damaging their physical and mental health. If you always keep this feeling of love, then your body is full of positive qi, which is the true qi of the ancients, as long as you have enough positive qi, health and longevity will certainly belong to you.
