What is the up-and-down dependency of the four figures?

Chinese medicine says that the rise and fall of the four human images depends on the changes in the four seasons of the year.

Four elephants take turns, once a year. Before Yang rises to half a year old, it rises to spring, and the spring temperature belongs to wood. Collapse has risen to summer, and summer heat is fire. After half a year, it falls in autumn, and autumn is cool. All belong to winter, and the air in winter is cold and belongs to water.

Spring is long and summer is long, and wood fire is also angry, so spring is warm and summer is hot; Autumn harvest and winter storage, golden water and gas, so autumn is cool and winter is cold. There is nothing special about the soil. The month of the four seasons has eighteen days each, and its commander-in-chief time is after the fire in June, which is called long summer. At this time, it is full of humidity, and the atmosphere of the native land is wet. The combination of earth and four elephants means five elements.
