Li Ka-shing

Nicknamed Superman, Li Ka-shing is revered as one of the most influential businessmen in Asia.

Li retired as chairman of CK Hutchison Holdings and CK Asset Holdings in May 2018 but remains senior advisor.

At the announcement of his retirement, Li joked that he'd been "working for a long time, too long."

His son Victor now heads the conglomerate, which has more than 300,000 employees and operates in more than 50 nations.

Li started Cheung Kong plastics, named after the Yangtze River, in 1950 at age 21 with $6,500 in savings and loans from relatives.

His Li Ka Shing Foundation has donated more than $3.3 billion; over 80% has gone to Greater China.
