When do the five elements, spring, summer, autumn and winter and the four seasons end?

A year is divided into four seasons: 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). A season lasts for 3 months, and the last month of each season is the end of the four seasons (that is, morning, evening, 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).
