When you ate the moon cakes on the Moon Festival, did you know anything about the moon cakes? Where did they come from? It was a story from Chu, Yuan-zhang. At that time, the Hans didn’t like the rules of the Mongols, so the Hans wanted to fight with them. On August 15, Chu started the war. A man, Liu, Po-wen, had a plan. He put the notes into the cakes and sent them to the partners. The notes said “Fight on August 15.” The Han people knew about the news by the cakes. Then it is the origin of the moon cakes.
