The Wing Wah restaurant started trading in a four-story building in Yuen Long which included a retail shop which sold its mooncakes.

The retail side of the business has grown, with branches all over Hong Kong selling Chinese sausage, cakes, and teas.

In the 1990s, the company built the eponymous Wing Wah Centre in its home district of Yuen Long, and continued opening shops in high traffic areas such as Hong Kong International Airport, and a multimedia tea museum at Ngong Ping on Lantau.

In 1960s, Hong Kong Wing Wah Cake Shop mainly concentrated on its bakery business and was reorganised into a limited liability company.

In the 1970s, Wing Wah founded its own retail outlets at different locations, including Hong Kong Island, Kowloon and the New Territories, in order to actively expand and promote its business.
