Introduction to Dongtai Hair Embroidery: Displayed in the first exhibition hall are large portraits of Liu Shaoqi and Chen Yi carefully embroidered with human hair on silk. Dongtai hair embroidery is a unique handicraft in Yancheng and an ancient oriental art. In the late 1970s, the long-dormant art of hair embroidery miraculously revived in Dongtai. The almost extinct ancient art was rejuvenated and bloomed with splendor.
