The first lunar month of the lunar calendar is the traditional Lantern Festival. The Lantern Festival, also known as the "Upper Yuan Festival" and "Spring Festival", is a traditional Chinese folk festival. The first month is the first month of the lunar calendar. The ancients called the night "宵", and the fifteenth day is the first full moon night of the year. Therefore, the fifteenth day of the first month is the Lantern Festival. After the Lantern Festival, China’s years are really over.
