Nanchong is the birthplace and one of the main producing areas of China silk. In a long history, "Shunqing Silk" is famous at home and abroad. 19 15 Nanchong Silk won the gold medal in Panama International Fair. Du Dong Hibiscus, the silk of Zhou State, is regarded as a national treasure by the Japanese royal family. Nanchong is one of the first "Silk Capital of China" cities named by China Silk Association and the only "Silk Capital of China" in the central and western regions.
Therefore, I think there is Shunqing silk in Shu brocade.
