According to a Harvard Business School article:
"From his humble beginnings in China as a teacher's son, a refugee, and later as a salesman, Li provides a lesson in integrity and adaptability. Through hard work, and a reputation for remaining true to his internal moral compass, he was able to build a business empire that includes: banking, construction, real estate, plastics, cellular phones, satellite television, cement production, retail outlets (pharmacies and supermarkets), hotels, domestic transportation (sky train), airports, electric power, steel production, ports, and shipping."
Today, Li's businesses cover almost every facet of life in Hong Kong, from electricity to telecommunications, from real estate to retail, from shipping to the Internet. The Cheung Kong Group operates in 55 countries and employs over 260,000 staff worldwide.
