In the Northern Song Dynasty, the ten stems and twelve celestial bodies were combined to mark the time. Until now, the years, months, days and hours were all marked with the stems and branches, and the stem and branch calendar became increasingly complete. Over the years, the Chinese stem and branch chronology and the calendar numeral chronology have both cooperated with each other and formed separate systems. Lunar calendar or solar calendar
