The traditional food of the Han nationality in China 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.

According to legend, during the Spring and Autumn Period and the Warring States Period, rice cakes spread in all directions from the capital of Wu State (now Suzhou City, Jiangsu Province). There is a folk saying in Ningbo that "rice cakes are rising year by year, and this year is better than last year".

People also use printed boards to press rice cakes into the shapes of Five Blessingg, Six Treasures, Money and Ruyi, symbolizing good luck and good luck.

Others are made into small animals such as "Jade Rabbit" and "White Goose", which constitute the perfect combination of content and form in the true sense.

According to legend, after Wu Zixu committed suicide at the end of the Spring and Autumn Period, Gou Jian, the King of Yue, sent troops to attack Wu, surrounded Gusu City, the capital of Wu, and Wu Jun was trapped in the city, with women and children crying in the streets.

Before he died, he said to his men, "If the country is suffering and the people are short of food, you can dig three feet under the city wall to get food." After Wu Zixu's death, his men were surrounded by Vietnamese troops, and many people starved to death because of the lack of food in the city. At this time, someone thought of Wu Zixu's words, so they went to dig the city wall and dug more than three feet deep. Sure enough, they dug up many edible "city bricks", that is, rice cakes, and won the battle.

It turns out that when Wu Zixu supervised the construction of the wall in Gusu City, he was ready to deal with the famine. From then on, every family made rice cakes and ate rice cake soup on New Year's Eve to commemorate Wu Zixu.
