The normal laws of climate change throughout the year are spring temperature, summer heat, autumn dryness and winter cold. Under the influence of climate change in four seasons, all creatures in nature will inevitably change accordingly, which is the natural law of Tibet in spring, summer, autumn and winter.

The physiological function of the human body is also in line with nature. If the metabolism of the body violates this law all the year round, the qi of the four seasons will hurt the five internal organs, that is, "cold in spring, heat in summer, dampness in autumn and typhoid in winter". Su Wen's Four Qi Tunes the Spirit says: "The four seasons of Yin and Yang are the foundation of all things and the foundation of life and death.

When the sun shines directly on the Tropic of Cancer, the northern hemisphere gets more solar heat, and the day is longer than the night, so the highest temperature in the northern hemisphere is summer.

At this time, the sun hangs obliquely in the southern hemisphere, getting less solar heat, and the night is longer than the day. Therefore, the southern hemisphere is in the coldest season of the year. When the earth revolves around the sun for half a week, the direct point of the sun moves from the tropic of cancer to the tropic of Capricorn, and the solar heat gained by the northern hemisphere gradually decreases, from summer to autumn, and then to winter;
