What is the Huangdi Neijing preserved by Song Meiling?
Song Meiling's Huangdi Neijing is a classic of women's health and beauty. Huangdi Neijing pointed out: "Autumn and March are originally tolerant, with urgent weather and bright tolerance. Early to bed and early to rise, happiness is with the chicken. Tranquilizing the nerves and delaying autumn punishment. Convergence calms autumn. No ambition, so the lungs are clear. This autumn air should be the way to keep in good health. The success of nourishing the heart makes Song Meiling perfect from the inside to the outside. Because Song Meiling has a moderate diet and doesn't eat much, the staff gave her a nickname, calling her a "cat belly beauty".
