Why do Tiantai people celebrate the Lantern Festival one day in advance?

On the fourteenth day of the first month, according to the custom of Tiantai people, today is the Lantern Festival. In other places, it is the fifteenth day of the first month, which is celebrated all over the world. Only the rooftop of the mountain city has designated the 14th day of the first month as the Lantern Festival, and all families, old and young, should eat "paste spicy cooking". What's going on here?

According to legend, during the Jingdezhen period of the Southern Song Dynasty, on the 14th night of the first month of one year, the lanterns in China were in full swing, and the natives went shopping and watched them with great interest. At this time, an old artist who fled from behind the nomads from the south of the Yangtze River came to Tiantai City with his granddaughter to make a living by singing. I fainted in the street because of long-term running and overwork. When an old Chen Man nearby saw it, he immediately scooped up two bowls of paste and sent it to him. After they ate it, they were refreshed and their eyes shone. They repeatedly said, "Bright eyes! Bright eye cream! "

Since then, Tiantai has had the custom of eating "spicy boiled" on the fourteenth day of the first month.
