'Mooncake' (yuè bǐng) is a traditional Chinese pastry eaten during the Mid-Autumn Festival. The character 月 (yuè) means 'moon', and 饼 (bǐng) means 'flat, round cake' or 'pastry' — together they literally mean 'moon-shaped cake'. These dense, rich pastries often contain sweet fillings like lotus seed paste, red bean paste, or salted egg yolk, symbolizing family unity and the full moon.

Mooncakes are typically given as gifts in elaborately decorated boxes and shared among family members during festive gatherings. While traditionally homemade, today they’re widely purchased from bakeries and specialty stores, with modern varieties including ice cream, chocolate, and even savory flavors. Their round shape reflects completeness and harmony in Chinese culture, making them central to Mid-Autumn celebrations across China and the Chinese diaspora.
