Most of the stalls from hawker centres are converted from former dai pai dong by strict regulations and management; the Hong Kong Government regards the provision of cooked food centres as a way to eliminate traditional dai pai dongs from local streets in the 1970s. During the industrial boom in the 1960s and 1970s, the government also built cooked food markets in industrial areas to serve the catering needs of the working class in major industrial centres such as Kwun Tong, Tsuen Wan and Fo Tan.
