Lee Ka-kit and Lee Ka-shing

Net worth: $30.4 billion

Peter Lee Ka-kit and Martin Lee Ka-shing became the joint chairmen of Henderson Land Development after their father, Lee Shau Kee, announced his retirement in May 2019. Lee Shau Kee co-founded the Sun Hung Kai with Kwok Tak-Seng, the late father of Hong Kong’s billionaire Kwok brothers. In 1976, Lee started Henderson Land, the flagship company behind the family’s $30.4 billion fortune. Lee, a philanthropist and was once ranked fourth on Forbes’ global rich list, also donated more than $400 billion toward education for years. He is also known as Hong Kong’s richest man.

Before the succession, Peter worked in Henderson in 1985 while Martin joined in 1993. Both of them became vice-chairmen of the company, Peter in 1993 and Martin in 2005. The Lee family controls five other listed companies that span sectors and has several private investments, and most of them are in mainland China. Henderson Land Development has about 6.4 million square feet of completed investment properties in mainland China, with the bulk in Beijing, Guangzhou, and Shanghai.
