The Mid-Autumn Festival is a traditional Chinese festival celebrated on the 15th day of the eighth lunar month. The mooncake is a key symbol of this festival, often filled with various ingredients like lotus seed paste, red bean paste, and fruits. The packaging design of mooncakes reflects cultural heritage and artistic creativity. Designers might incorporate elements from Mid-Autumn Festival legends, such as the moon goddess Chang'e, or traditional patterns, to enhance the cultural significance and aesthetic appeal.
