Chagan Lake in Songyuan City, Jilin Province has a fishing and hunting culture that has been passed down for thousands of years. Fish skin painting is one of the Chagan Lake fish skin products.

During the Spring Festival this year, they rushed out more than 400 such orders as scheduled. The "Four Major Techniques" give latecomers a set of rules to follow when learning fish skin painting. A set of blue flower-style necklaces, rings, pendants, and earrings are particularly eye-catching.
