However, the officers and men of the imperial court searched very closely and it was very difficult to pass on the news. Liu Bowen, a military strategist, came up with a plan and ordered his men to hide a note with the words "Uprising on the 15th of August" in the cake, and then sent people to the uprising troops in different places to inform them to respond to the uprising on the 15th of August. On the day of the uprising, all the rebels responded together.
Soon, Xu Da captured the Yuan Dynasty and the uprising was successful. When the news came, Zhu Yuanzhang was overjoyed and quickly sent a message saying that all the soldiers should have fun with the people in the upcoming Mid-Autumn Festival, and they should give the "moon cakes" secretly sent at the time of the war as seasonal cakes to the ministers. Since then, the making of "moon cakes" has become more complicated and varied. Since then, the custom of eating moon cakes in the Mid-Autumn Festival has spread among the people.
Watching the moon and eating moon cakes is an essential custom in Mid-Autumn Festival in all parts of China. As the saying goes, "Moon cakes are sweet and fragrant when they are full on August 15th". The word moon cake originated from Liang Lumeng written by Wu in the Southern Song Dynasty, when it was just a snack. Later, people gradually associated moon viewing with moon cakes, symbolizing family reunion and bearing their thoughts. At the same time, moon cakes are also an important gift for friends to contact their feelings during the Mid-Autumn Festival.
