During the Tang Dynasty, mooncakes were introduced. Mooncakes were originally a form of tribute offered to the emperor, but during the Tang Dynasty, they became a symbol of unity and good fortune. The tradition of exchanging mooncakes among family members and friends began during this time, signifying reunion and harmony.
Traditionally, they are round to symbolize the full moon and family unity. The filling often includes lotus seed paste, red bean paste, salted egg yolks, and sometimes even fruits, nuts, or meats. Mooncakes are not only delicious but also intricately designed, with decorative patterns on their crusts that represent various blessings, such as longevity, prosperity, and happiness.
