月饼 (yuèbǐng) is a traditional Chinese pastry typically enjoyed during the 中秋节 (Zhōngqiū Jié), or Mid-Autumn Festival. These round cakes symbolize reunion and completeness, reflecting the full moon's shape. They are often filled with various ingredients, such as 红豆沙 (hóngdòushā) (red bean paste), 莲蓉 (liánróng) (lotus seed paste), or 五仁 (wǔrén) (mixed nuts). During the festival, families gather to share mooncakes and admire the moon, celebrating togetherness. Mooncakes are often beautifully packaged and given as gifts, making them a popular choice for expressing good wishes. The custom of eating mooncakes has a long history, dating back to the 唐朝 (Táng cháo) (Tang Dynasty).
