Siyi cake making skills are a traditional skills project in the fifth batch of representative projects of Nantong's municipal intangible cultural heritage. The "Siyi cake" making skills are the general term for the cake making skills of Siyi Cake Shop, a century-old shop in Nantong. The characteristics of its cake making skills are "wet grinding, fine screening, double high steaming, and water locking".
