How did the custom of eating moon cakes on Mid-Autumn Festival come from?

Moon cakes symbolize reunion and are essential food for the Mid-Autumn Festival.

According to legend, during the Yuan Dynasty, the broad masses of people in the Central Plains rebelled against the cruel rule of the Mongols. Zhu Yuanzhang wanted to unite the resistance forces, and the officers and men of the Yuan Dynasty searched closely, but the news could not be transmitted. So Liu Bowen came up with a plan, ordered Wang Zhaoguang to make a cake, and hid a note with the words "August 15th Uprising" in the cake. Then they were sent to the uprising troops in various places, informing them to respond to the uprising on the evening of August 15. Therefore, the Yuan Dynasty was overthrown in one fell swoop.
