Legend has it that the Lantern Festival originated in the Western Han Dynasty, and Emperor Wu of the Han Dynasty sacrificed to Taiyi God at Ganquan Palace on the 15th night of the first month. After Buddhism was introduced into China, Emperor Hanming ordered the palace and temple to "light lanterns to show Buddha" on the 15th night of the first month, and the custom of decorating lanterns spread, so the Lantern Festival was also called "Lantern Festival". Lantern Festival was also called Shangyuan Festival in ancient times. Legend has it that a long time ago, there were many fierce birds and beasts that hurt people and livestock everywhere, so people organized themselves to beat them. A god bird was trapped and landed on earth, but was accidentally shot dead by an unsuspecting hunter. The Emperor of Heaven was very angry when he learned about it. He immediately sent a decree and ordered the heavenly soldiers to set fire to the earth on the 15th day of the first month, and burned all the human and animal property. The daughter of Emperor Tiandi was kind-hearted. She couldn't bear to see the innocent suffering of the people, so she risked her life and secretly drove Xiangyun to the world to tell people the news. When people heard the news, it was like a thunderclap on their heads. I was so scared that I didn't know what to do. It was a long time before an old man came up with an idea. He said, "On the 14th, 15th and 16th of the first month, every family decorated their houses, lit firecrackers and set off fireworks. In this way, the emperor of heaven will think that people have been burned to death. "
