Zhang Yin

Zhang Yin, founder and director of the family company Nine Dragons Paper Holdings, topped the 2009 Hu Run list of the richest women in China.

Her company imports scrap paper from overseas and turns it into cardboard boxes to export Chinese goods.

Zhang Yin opened a paper trading company in Hong Kong in 1985. In 1990, she set up a paper exporting Chung Nam in America. Chung Nam became the largest supplier of paper materials in Europe and America. In 1996, Zhang set up the Nine Dragons Paper Holdings in Dongguan, Guangdong Province. By 2005, the company had become the largest paper maker in China. In 2006, the company was listed on the Hong Kong stock exchange.

In 2008, Zhang courted controversy when she opposed parts of China's new Labor Law that enhanced workers' rights. Some NGOs have raised concerns about working conditions in Nine Dragons plants.
