The rice cake is a traditional food of Han nationality in China, which belongs to the seasonal food of the Lunar New Year. Rice cakes are made of rice or glutinous rice, boiled into rice, beaten with water or ground into powder, and pressed. During the Spring Festival, many areas in China pay attention to eating rice cakes. There are three colors of rice cakes: red, yellow and white, which symbolize gold and silver. The rice cake is also called "rice cake", which is homophonic with "getting taller every year", meaning that children are getting taller every year.

The legend of rice cakes:

In the ancient Spring and Autumn Period and the Warring States Period, wars continued year after year. Wu Zixu, a doctor of the State of Chu, went to Wu to avenge his father, intending to borrow soldiers to attack the State of Chu. The king of Wu did not agree, so Wu Zixu killed the king of Wu, led the troops to attack the capital of Chu, and set up a new king of Wu to reign, and Wu Zixu was also granted land.

In order to prevent aggression, Wu Zixu led people to build the famous city of He Lv. After the city was repaired, he said to his confidant, "After my death, if the country is in trouble and the people are hungry, you can dig a few feet under the city gate to find food." Soon, Wu Zixu was trapped and committed suicide. The State of Yue took the opportunity to attack the State of Wu, and the war continued, and there was famine everywhere.

In times of crisis, someone remembered Wu Zixu's entrustment before his death, so they secretly tore down the city wall and dug up the ground. It turned out that the city foundation was made of bricks and stones made of glutinous rice, and people used it to make a kind of food, which helped them overcome their difficulties. This kind of food was later called rice cake.
