By the way, there are three treasures in Shanghai, namely jade, double-sided embroidery, and Lin Yunniang. Jade is produced in Shencheng. There are also many jade merchants. Every year, jade tributes are sent to the palace here. This double-sided embroidery is to embroider two things on one cloth at the same time. For example, if you embroider a doll on one side, you can embroider a landscape on the other side. This is also unique to Shencheng people. But who is this Lin Yunniang and why can she be called the Three Treasures of Shencheng? This Lin Yunniang is Lin Shangshu's only daughter. All of Lin Shangshu's ancestors were officials, and he came from a family of bureaucrats. Their descendants are all officials in the court, and the Lin family is also a big family in Shencheng. This Yun Niang was beautiful and was said to be the reincarnation of a fairy, so she was classified as one of the Three Treasures of Shen City.
