Property tycoons Robert and Philip Ng have an estimated net worth of $7.7 billion as of September 2015, according to Forbes. Because of the dull real-estate business in Hong Kong and Singapore, the sibs’ bundle has significantly dropped. However, their massive wealth is obtained largely from the Hong Kong-based Tsim Sha Tsui Properties, where Robert Ng saved as Chairman. Additionally, he is serving as the Chairman of Sino Group since 1981. Today, Sino Group is considered as one of Hong Kong’s leading property companies. It’s comprised of three publicly traded companies which are run from the Ng family. The group is involved with the development of residential as well as commercial infrastructures as well as industrial, office, and retail properties. In addition they spend money on club direction, as well as resort development and direction.
