Traditional Chinese calligraphy and painting have a long history and feature a unique artistic style. As Chinese people grow more confident in traditional Chinese culture, younger generations in this country are becoming increasingly interested in calligraphy and painting and relevant knowledge. This study conducted field research to analyze and investigate the distribution of young people’s interests, the platforms they use to communicate, and the characteristics of this group of people, with a focus placed on their interests in traditional calligraphy and painting. The storyboard method from service design was employed to delve into user needs. The Yijie App, an online communication platform, has also offered offline sales of mystery boxes containing various products for both calligraphy and painting enthusiasts and mystery box fans to appreciate or collect. The online points redemption system transforms virtual mystery box culture into tangible cultural and creative products, which can serve as an economic foundation for online platform operations and attract more users to participate in the interaction provided by the App. As global digitization and 5G technology advance, the Yijie App further develops and spreads these traditional Chinese art forms via the Internet and brings the art closer to young people.
