The majority of Cai's wealth is derived from a stake in Longfor Properties, a Beijing-based developer. Cai was married to Chinese billionaire and Longfor Chairman Wu Yajun until their divorce in 2012, when they split a jointly held 75.6 percent stake. Wu took 45.4 percent and Cai 30.2 percent. After stake sales in 2016 and 2019, he now holds a stake of 23 percent, according to a January 2019 Hong Kong exchange filing. Cai holds his Longfor shares through a family trust.
The value of his cash investments is based on an analysis of dividends, insider transactions, taxes and market performance.
Shao Yuqun, a spokeswoman for Longfor declined to comment on the net worth calculation.
Cai was born in January 1963 in Chongqing, China's largest municipality. In 1992, he married his future business partner Wu Yajun, who is also from Chongqing, quitting his job at a state owned airplane maker in Chengdu to start a trading company in their hometown. Wu left her job working as a journalist for a real estate newspaper a year later.
The couple encountered a series of problems when they bought their first apartment, an 80-square-meter flat (861 square feet) in Chongqing. The closing was delayed for a year, natural gas wasn't available, the lighting was poor and the elevator service hours were limited. The experience led them to open a business that would build better homes in China and in 1994 they founded the predecessor of Longfor Properties.
Longfor sold its first residential project in 1997 for $157 per square meter, more than double the average household income in China at the time. Since then, Wu, its chairman, has expanded Longfor into 13 other Chinese cities and moved its headquarters to Beijing. The company raised $1 billion in a 2009 initial public offering in Hong Kong.
They divorced in 2012 and Cai took about 40 percent of Longfor shares the couple used to own together, and left his executive role at the property developer.
