0 1 moon cakes symbolize family reunion, because the Mid-Autumn Festival is meant for family reunion, but when it was first invented, it was not for people to eat. At first, it was just a tribute to the moon god, and later it gradually evolved into people's food, and it can also be used as a gift for relatives and friends.
According to legend, moon cakes originated in the Tang Dynasty. During the reign of Li Yuan in Tang Gaozu, General Li Jing conquered Xiongnu and returned home in triumph. At this time, Turpan people who were doing business passed by Chang 'an and brought gifts to Tang Gaozu. The emperor opened it and found some edible round cakes, so he gave them to the ministers. August 15 is the Mid-Autumn Festival. Later, during the reign of Li Longji, Emperor Xuanzong of the Tang Dynasty, he changed the round cakes into moon cakes because Li Longji thought he would eat moon cakes on the Mid-Autumn Festival.
It was only in those days that ordinary people couldn't afford moon cakes, not because they were so expensive, but because they were considered as food only for nobles. In the Ming Dynasty, mooncakes became very common and could be eaten by every household, so only in the Mid-Autumn Festival did people visit relatives and friends and bring mooncakes to their friends. It is precisely because the custom of eating moon cakes was carried forward after the Mid-Autumn Festival in the Ming Dynasty that this custom was handed down everywhere and has been handed down to the present.
