"Supporting cakes" is a dietary custom in the Spring Dragon Festival corresponding to "February 2". As we all know, on February 2nd, most folk foods are named after "Dragon". For example, northerners eat jiaozi as "eating dragon ears", rice as "eating dragons", wonton as "eating longan", noodles as "supporting dragon whiskers", and steamed cakes are also shaped like dragons' bones on the surface, which shows respect for the descendants of dragons. So, what is the connection between "supporting cakes" and dragons? Speaking of it, there is another interesting legend: it is said that human beings have suffered for a long time and the people are miserable. Yulong, who is in charge of Tianhe, moved with compassion and sprayed rain on the world. Provoked the jade emperor into great anger and took Yulong down the mountain. In order to repay Yulong for saving his life, people were afraid that Yulong would be crushed to death, so they made a big glutinous rice cake and held it under Yulong's waist. After Yulong was rescued from the sky, he distributed the cakes to everyone in order to thank everyone in the world. After eating the supporting cake, people will be extremely powerful, able to bear the busiest farm work and the most troublesome things in the world.
