Property tycoons Robert and Philip Ng have an estimated net worth of $9.8 billion as of March 2017, according to Bloomberg. Due to the sluggish real estate industry in Hong Kong and Singapore, the siblings' fortune has significantly dropped. Nonetheless, their massive wealth is acquired mostly from the Hong Kong-based Tsim Sha Tsui Properties, where Robert Ng saved as Chairman. Also, he has been serving as the Chairman of Sino Group since 1981.

Today, Sino Group is considered as one of Hong Kong's leading property companies. It is comprised of three publicly traded companies that are run by the Ng family. These companies include Tsim Sha Tsui Properties Limited, Sino Hotels (Holdings) Limited, and Sino Land Company Limited.

The group is involved with the development of residential and commercial infrastructures as well as industrial, office, and retail properties. They also invest in club management, as well as hotel development and management.
