TCM health preservation is to make appropriate adjustments according to the laws of Huangdi Neijing, so as to adapt to the natural ecological environment and conform to Scientific Outlook on Development. Health preservation is the climate change and weather change in 24 solar terms from beginning of spring to Great Cold. Warm in spring, hot in summer, cool in autumn and cold in winter are inseparable from food, clothing, housing and transportation. You can't go against the natural ecological environment with people's subjective consciousness, but follow it. Only by following it can you live a long and healthy life! ! ! But now the serious destruction of the ecological environment and global warming have led to extreme weather, which has seriously tested our health. This is the result of willful disobedience to the natural ecological environment! ! !
