Supplementing Yang Can with food or self-cultivation. In fact, there is no need to eat any fancy food, mainly rice. People who didn't have any vegetables before can grow very healthy if they eat more rice and miscellaneous grains. Then, you can eat herbal soup and some Chinese patent medicines. Such as Buzhong Yiqi Pill, Shiquan Dabu Pill and Guifu Dihuang Pill. Yang is the fire of human body, and fire rises above water. If the kidney yin is insufficient, there will be a so-called virtual fire, which is also a lack of yang. If the body is overworked, or often stays up late, it must be yin and yang deficiency, which needs to be supplemented. I will make this point clear dialectically.
Spiritual sun be the spirit, is to work less, less, less. Get in touch with nature, such as watching the sky, watching the stars and basking in the sun. You can also read books and classics, such as Tao Te Ching, Analects of Confucius and Diamond Sutra, including the Bible. You can also listen to more light music. It's just that it doesn't take a day or two to damage the body's yang, and it certainly doesn't take a day or two to make up for it. The important thing is to persevere.
