People often say that "spring" lasts for several days, minutes and seconds. How is this time calculated?

It is often said that "playing spring" is one of the solar terms customs in beginning of spring, so the time is the same as that in beginning of spring. It is the beginning of a year in the official calendar, the beginning of the end of all things, and represents the meaning of the beginning of all things and all self-improvement.

In the past, people made spring cattle out of clay the day before beginning of spring's birthday, and beginning of spring whipped them with red and green whips, so this custom was called "playing spring". In the folk, people held a ceremony of "whipping spring cattle" in beginning of spring that day to welcome the arrival of spring and pray for a bumper harvest. In the old days, unemployed people in Hunan beat gongs and bamboo boards around the Spring Festival, singing lyrics and asking for money from house to house, which was called playing spring.
