The Winter Solstice, also known as Dongzhi, is a traditional Chinese festival that falls on the 21st or 22nd day of December. Zongzi, a sticky rice dumpling, is a popular food associated with this festival. The design of Zongzi packaging often reflects traditional Chinese culture, incorporating elements like calligraphy, paintings, and symbols of prosperity and happiness. This includes the use of auspicious motifs, seasonal decorations, and cultural iconography. The packaging also aims to be eco-friendly, using biodegradable materials, and may feature innovative designs to attract consumers and preserve cultural heritage.
