This set of Sanxia postcards are based on the featured products and culture of Sanxia. The set includes six patterns: Biluochun, Oldham Bamboo Shoot, Indigo Dyeing, Old Street, Arch Bridge, and Zushih Temple.
The base card has front- and back-side patterns and a sticker. The design of the sticker allows for interaction between the sender and recipient; the user can place the sticker wherever they wish. “To XXX: Come to Sanxia!” A tone for inviting friends is used to recommend others to come to Sanxia.
