An official default of China Evergrande means the company may not be able to restructure debt at a lower cost, and may trigger a widespread default and short-term pressure of property prices due to asset sale. China Evergrande is founded in 1996 by Hui Ka Yan (Xu Jiayin). In 2009, China Evergrande went public in Hong Kong. At one point, Hui Ka Yan had a personal fortune of more than $30 billion.
