Cheng Yijun, 28, from Guangdong Province

Cheng’s father, Cheng Minghua, owns a market named “Daying” for fashion wholesalers, which opened in 2008 at the start of global financial crisis. The senior Cheng struggled to maintain his business. Cheng Yijun joined his father after graduating with his bachelor’s degree, and they rented their room to e-commerce wholesalers.

Daying is now the largest online vender center in Guangdong. Over the past few years, a number of multimillionaires have come out of the center, which earns 7 billion yuan ($1.1 billion) annually, including 5 billion yuan ($786 million) in e-commerce sales.
