Designing a milk powder packaging that integrates Yi ethnic culture and the elements of the Sun Calendar, our aim is to create a unique brand image while showcasing the product's traditional roots and cultural depth to consumers. We delve into the uniqueness of Yi ethnic culture and the Sun Calendar to ensure that the symbols and patterns used in the design appropriately represent the Yi's art. We select the symbolic concept of time growth from the Yi Sun Calendar and use it as the visual focus of the packaging to convey the idea of the product's harmonious coexistence with nature. On the packaging, we clearly display product information, including the brand name, product features, nutritional value, and freeze-dried powder technology, ensuring that the information is easy to read and does not conflict with the Yi ethnic cultural elements. With this design concept, we have created a milk powder packaging that not only showcases the characteristics of Yi ethnic culture but also possesses modern aesthetics. Such packaging is not only able to attract consumer attention but also conveys the product's traditional values and the brand's unique personality.
