Explain the practical application of Wang Xiang's death.

In spring (after beginning of spring), wood is the most prosperous, because in spring, the soil is the most declining, because the soil is mainly wood in season.

Summer (after the long summer) is the most prosperous, because summer fire is the season, and gold is the most declining, because gold is submerged by the prosperous fire of the season.

Autumn (after beginning of autumn) is the most prosperous golden season, because autumn gold is the season, and wood is the worst, because wood is dominated by the prosperous gold of the season.

Water is the most prosperous in winter (after beginning of winter), because the water in winter is in season, and the fire is the worst, because the fire is submerged by the prosperous water in season.

The five elements of the earthly branch are in the morning before the ugly month, that is, the last month of the four seasons. At this time, the earthly branch is in season and the water is the most prosperous, because it is caused by the earthly branch.

The change of four seasons, due to the different length of cold, warm, dry and wet days and nights, so the five elements also change due to natural changes. When people prosper, people decline, and when people decline, people prosper, and so on. Due to the mutual restraint of the five elements, in the same period, the prosperity and decline of the five elements are completely different, only one line is the most prosperous and the other is the most declining.
