The Mid-Autumn Festival is one of the most important festivals in China, which is celebrated on the 15th day of the eighth month of the Chinese lunar calendar.

The festival dates back to the Southern Song Dynasty. In the Southern Song Dynasty (1127-1279), people sent round moon cakes to their relatives as gifts in expression of their best wishes of family reunion. This day was also considered as a harvest festival since fruits, vegetables and grain had been harvested by this time and food was abundant.

The Mid-Autumn Festival is an evening celebration when families gather together to eat moon cakes,which are the special food for this festival, and enjoy the round moon. They can look back on the past and look forward to the future together. On that night, the moon appears to be at its roundest and brightest. The full moon is a symbol for family reunion, which is why that day is also known as the Festival of Reunion.
