After graduating from high school, Sun Aixiang spent nearly two decades selling plastics and adhesive products such as glue and tape. A shrewd decision to establish a materials company with his brother-in-law Zhao Jianping in 2003 has now made both men billionaires on paper, following Shenzhen HFC’s blockbuster listing and a first-day share price surge of as much as 719%.

Sun, the company’s 58-year-old chairman, has amassed an estimated fortune of $1.7 billion from his stake in the company, following its listing on the Shenzhen Stock Exchange, according to Forbes estimates. Zhao, a 63-year-old company director, is worth an estimated $1.3 billion based on his stake.
