How do you remember the year of the lunar calendar in China?

During the period of Three Emperors and Five Emperors, the lunar calendar recorded the years according to the names of kings. From the summer, the title of the year was recorded according to the title of the king, and from the Qin Dynasty, the title of the year was recorded according to the title of the emperor. From the beginning of Emperor Wu of the Han Dynasty, the first year number "Jianyuan" appeared. Probably in the Qing Dynasty, the year number was recorded by the temple number, and in the Republic of China, it was recorded by the country number. During the Republic of China, the Gregorian calendar was used, and the lunar calendar had no year number. So some people began to talk nonsense and record the year with dry branches. There are some mistakes and problems in the use of the year of the lunar calendar, because the year of the lunar calendar is based on beginning of spring and the first day of the first lunar month. Therefore, there were some mistakes before and after beginning of spring. For example, before the Spring Festival in beginning of spring, the years of cadres and party branches were changed in advance, but after the Spring Festival in beginning of spring, there was a problem that the years of cadres and party branches should be changed to beginning of spring without change. This is the problem of borrowing cadres to support the year in the lunar calendar. So we should make it clear that the dry calendar and the lunar calendar are different. Elephant trunk calendar is ephemeris, which depends on the orientation of Beidou bucket handle. beginning of spring is the beginning of a year. The lunar calendar is a lunar calendar, which cycles according to the phases of the moon. The first day of the first month is the beginning of a year.
