The company was first established in 1950 by Lau Pui Ling 劉培齡 and 趙聿修. The Wing Wah restaurant started trading in a four-storey building in Yuen Long which included a retail shop which sold its mooncakes etc. The business incorporated in 1962. In 1963, it launched a new mooncake made from white lotus paste. The Wanchai branch was opened in 1967, and a larger restaurant was opened in Yuen Long in 1975.
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.
