W ang Miaotong is a Chinese billionaire whose wealth is derived from her family's stake in the chemical company Zhejiang Longsheng Group. The company is a global leader in the production of textile dyes, particularly disperse dyes, which are used to color polyester and other synthetic fibers. Her brother, Ruan Shuiliang, is the chairman and public face of the company.

While not involved in the day-to-day management of the chemical giant, Wang's fortune is intrinsically linked to its success. The family has built a powerful, vertically integrated chemical enterprise that benefits from the massive scale of the global textile industry. The company has also diversified its operations into other specialty chemicals and has a significant real estate arm. Her ownership stake in the family-controlled, publicly traded business is the source of her considerable fortune.
