W ang Wei is a famously low-profile Chinese billionaire who is the founder and chairman of SF Holding, the parent company of SF Express, China's largest and most dominant package delivery and logistics company. He is often referred to as the "FedEx of China." He founded the company in 1993 in southern China as a small courier service, initially focused on the then-illicit business of shuttling packages between Hong Kong and the mainland.

He has since built SF Express into a massive and highly respected logistics powerhouse, known for its focus on premium service, its own fleet of cargo aircraft, and its extensive delivery network. While the rise of e-commerce fueled the growth of many of its low-cost rivals, SF has maintained a strong position in the more profitable business-to-business and premium document delivery segments. Wang took the company public on the Shenzhen Stock Exchange through a reverse merger in 2017, a deal that made him, for a time, one of the richest men in China. He is known for being extremely private and has rarely given media interviews.
