Fire: Summer. Fire, which started in the long summer, flourished in the afternoon (summer solstice is extreme) and stopped in summer.
Kim: Autumn. Gold begins in Shen (beginning of autumn), prospers in Unitary (autumnal equinox), and grows in cold dew.
Water: Winter. Water begins in Hai (beginning of winter), thrives in Zi (extreme winter) and is based on ugliness (slight cold).
Earth: Represents the four seasons. Born in the four seasons, at the end of the four seasons: Chen, Wei, Xu and Ugly are all soil.
The ancients said that there are four seasons in a year, spring belongs to wood, summer to fire, autumn to gold and winter to water. Because everything is original, the four seasons flow and merge into five elements. The specific correspondence is: spring: the first month (cloudy), February (gross) and March (Chen). Summer: April (last), May (noon) and June (last). Autumn: July (Shen), August (especially) and September (Xu). Winter: October (Hai), November (Zi) and December (Ugly).
Extended data A season lasts for 3 months, and the last month of each season is the end of four seasons (that is, morning, late month, full moon and ugly month). These four months and five elements belong to the earth, which is the monthly order of Tuwang! Therefore, "the king of the earth is at the end of the four seasons" (that is, the king of the earth is in the last month of each of the four seasons).
The Five Elements is a systematic view of China's ancient Taoist philosophy, which is widely used in traditional Chinese medicine, geomantic omen, numerology, physiognomy and divination. The meaning of the five elements includes five basic trends in the evolution of Yin and Yang: water (moistening the lower part), fire (burning the upper part), gold (converging), wood (prolonging) and earth (neutralizing).
