Cheng's golden years of growing up

After leading Chow Tai Fook Jewellery for more than five decades, Cheng Yu-tung decided to give the family business a new look by listing it in the stock market.

The 86-year-old Hong Kong tycoon, who is also in the property, transport, hotel and casino businesses, describes Chow Tai Fook as 'the most valuable asset' for him as it is what he had started out with to establish a business empire.
