Sai Kung Town is a former fishing village and market township. The designation of the country park areas during the 1970s was a huge boost to the local tourist industry. Sai Kung town underwent significant expansion during the 1970s when the High Island Reservoir and associated water scheme required some villagers and fishermen to be rehoused in Sai Kung. This provided a core of government-funded new development, both housing and commercial, in the town centre. This was followed by the Tui Min Hoi (literal translation 'over the harbour') development under the government's market town programme.
