In Chinese culture, roundness symbolizes completeness and togetherness. A full moon symbolizes prosperity and reunion for the whole family. Round mooncakes complement the harvest moon in the night sky at the Mid-Autumn Festival. 

The mooncake is not just a food. It's a profound cultural tradition deep in Chinese people's hearts, symbolizing a spiritual feeling. At Mid-Autumn Festival people eat mooncakes together with family, or present mooncakes to relatives or friends, to express love and best wishes.
