Seventy years ago in Chaozhou,Guangdong,Mr.Li was born into a well-educated family which instilled in him early on a respect for education and a wish to gain more knowledge.In 1940,when he was 12 years old,his father Mr.Li Yunjing decided to move the whole family to Hong Kong.Though by doing so they could avoid the wartime turbulence in the mainland,the senior Mr.Li,in poor health,found it difficult to settle in a new place and passed away in 1943.This meant that when Mr Li Ka-shing was only 15,he had to shoulder the responsibility of supporting his mother and younger siblings.He first worked for a firm manufacturing watchstrap,then became a salesman of plastic products.Because of his hard work,he was soon promoted to manager and,later,general manager.In 1950,with his own savings,he set up a plastics factory named “Cheung Kong” on Hong Kong Island,thus beginning his illustrious career in the business world.In 1957,accurately foreseeing a growth in demand,he established Cheung Kong Industrial Company Limited,specializing in plastic flowers and toys.In the following year,he made his first venture into the real estate business and,by the age of 30,had made a name for himself in Hong Kong as a successful businessman.Today,Mr.Li controls four publicly listed companies,namely,Cheung Kong (Holdings) Limited,Hutchison Whampoa Limited,Cheung Kong Infrastructure Holdings Limited,and Hongkong Electric Holdings Limited,with a combined market capitalization of approximately HK$450 billion.Based in Hong Kong,the Group has major investments and operations in over 24 countries around the world,including the United States,Canada,United Kingdom,Germany and France.Businesses encompass such diverse areas as property development and investment holdings,estate management and real estate agency,securities investment,hotels,container terminals,retail,manufacturing,telecommunications,infrastructure projects and materials,transportation and energy.
