In China's traditional medical theory, the root cause of illness is attributed to the vitality of the human body. This exuberant vitality is actually the "righteousness" advocated by Wen Tianxiang, which is what Mencius often said. However, various climate changes in nature are considered as the external causes of human illness. These external causes are attributed to "wind, cold, heat, dampness, dryness and fire", also known as "six evils". Strong vitality, external six qi will not harm the body; On the contrary, the body itself is weak, and the six evils will take advantage of it and naturally induce diseases.

Wen Tianxiang said in Song of Righteousness that he was shut up in a small hut. When he wrote this poem, it happened to be summer, and all kinds of smells such as humidity, decay and heat came in alternately from time to time, and ordinary people would definitely be unbearable to stay in it. But Wen Tianxiang said that he has always been very fragile, but it was in this environment that he survived two years. Why is this happening? So he concluded that this is because, like Mencius, he is "good at cultivating my noble spirit".

Kindness is the nutrient of mental health.

If you are kind, you will take pleasure in the happiness of others and be willing to help the poor, and your heart will often feel gratified; If you are kind, you will be kind to others, get along well with each other, and your heart will always feel happy; If you are kind, you will be aboveboard, willing to open your heart to others, and your heart will often feel relaxed. In short, a kind-hearted person will always keep a calm mind, and can adjust the blood flow and the excitement of nerve cells to the best state, thus improving the body's disease resistance. Therefore, kindness is an indispensable advanced nutrient for mental health.

Tolerance is the regulator of mental health.

People will inevitably suffer losses, be misunderstood and be wronged in social communication. Faced with these, the wisest choice is to learn to be tolerant. Tolerance is a good psychological quality. It not only contains understanding and forgiveness, but also shows tolerance and mind, strength and firmness. A person who is intolerant but only demanding of others is often in a state of mental tension, which leads to nervous excitement, vasoconstriction and high blood pressure, thus leading to a vicious circle of psychology and physiology. If you learn tolerance, you will be strict with yourself and be lenient with others, which is equivalent to putting a regulating valve on your mind.

Optimism is the key to mental health, Dan.

Optimism is a positive personality and mentality. It can stimulate people's vitality and potential, solve contradictions and overcome difficulties; Pessimism is a kind of negative and decadent personality and psychological state, which makes people sad, irritable and painful, helpless in the face of difficulties and affects their physical and mental health.

Indifference is an immune agent for mental health.

Indifferent, that is, indifferent, not pursuing fame and fortune. At the end of Qing Dynasty, Zhang Zhidong's Health Club said: "Nothing will make you feel at ease"; Bing Xin, a famous contemporary writer, also believes that "people are just without desire." This shows that indifference is a lofty realm and mentality, and a deep-seated orientation for the pursuit of life. With an indifferent attitude, he will not follow the trend and pursue fame and fortune in the secular world; You won't be ecstatic about what you have gained outside, but you will be deeply saddened by the loss; You won't complain about the world and others, and you won't be jealous. Indifferent mentality makes people always in a peaceful state, keep a normal heart, and all factors harmful to physical and mental health will be repelled.

Sun Chou asked Mencius why he was so single-minded and so calm about his beliefs.

Mencius said, "I am good at nurturing my noble spirit."
