1, Shangyuan Festival is the 15th day of the first lunar month, which is the traditional Lantern Festival in China. The first month is January, the ancients called the night night, and the fifteenth day is the first full moon night in a year, so the fifteenth day of the first month is called the Lantern Festival. Also known as Shangyuan Festival.

2. The Lantern Festival originated in the Han Dynasty. It is said that it was set in memory of Pinglu when Emperor Wen of the Han Dynasty. After the death of Liu Ying, Emperor Hui of Han Dynasty, Lv Hou usurped power, and the Lushi clan dominated the state affairs. After Lv Hou's death, zhou bo, Chen Ping and others eliminated Lv Hou's influence and established Liu Heng as the Chinese Emperor. Because the day to quell Zhu Lu was the fifteenth day of the first month, after that, every year on the night of the fifteenth day of the first month, Emperor Wendi went out of the palace incognito and enjoyed himself with the people as a souvenir. And the fifteenth day of the first month is designated as the Lantern Festival. During the reign of Emperor Wu of the Han Dynasty, the sacrificial activities of Taiyi God were held on the 15th day of the first month. Sima Qian listed Lantern Festival as a major festival in taichu calendar.

3. Of course, with the changes of society and times, the customs and habits of Lantern Festival have changed greatly, but it is still a traditional folk festival in China.

4. Yuanxiao, originally meant to be the night of Shangyuan Festival, was mainly about eating glutinous rice balls and enjoying the moon in the evening on the fifteenth day of the first month. Later, the name of the festival evolved into Lantern Festival. On the night of Lantern Festival, the streets are decorated with lanterns, and people enjoy lanterns, solve riddles on the lanterns and eat Lantern Festival, which will push the celebration activities that began on New Year's Eve to another climax and become a custom that lasts for generations.
