But it is not unique to Yangjiang. There is a very popular children's song in Guangdong: "Twisted, round chrysanthemums, fried rice cakes and glutinous rice balls, and my grandmother calls me a dragon boat. I don't care about chickens, they are big. How much do you sell it for? Sold 365 cents. " It shows that Guangdong has the custom of making fried rice cakes during the Spring Festival.

Legend has it that at the end of the Song Dynasty, there was an old woman in the countryside near Yangjiang City. One day, she got a lot of crispy rice that people abandoned. She took it back and soaked it in the soup. After eating for two days, she put the crispy rice on the roof to dry, and then used it as dry food when she couldn't eat. She took out the rice crust she had stored before that day to satisfy her hunger and ate the sugar she got from it. The old woman kneaded the leftovers into a ball and dried them for the next meal. Mrs. Wu's "powder cake" has since spread in the society and become the embryonic form of today's fried rice cake.
