the city under the moon, the story under the moon. When love is full of life, the idea is only to give a good moon cake to my dear family-Aishang; The city under the moon, the story under the moon. Moon cakes, a traditional snack of the Han nationality with a long reputation, are deeply loved by the people of China. They are round in shape and shared by the whole family, so they symbolize reunion and harmony, and they are a must-eat on the Mid-Autumn Festival.
