Yim Tin Tsai is named after the saltpans on the island. It also commemorates the hometown of the ancestors located in what is now Yantiangang, Shenzhen three centuries ago. After settled in Yim Tin Tsai, the original villagers made a living by harvesting salt. At its height, the saltpans had reached a total area of six mu (0.4ha), with enough output to supply the entire Sai Kung district. For various reasons, the villagers on the island later abandoned the saltpans, and the pans were converted into fish ponds in the 1980s. In 2010, The Salt and Light Preservation Centre, a subsidiary of the Yim Tin Tsai Village Rural Committee, actively revitalised some of the saltpans, successfully retaining and reconstructing the original appearance of the pans. The revitalisation of the saltpans of Yim Tin Tsai was honoured with the “Award of Distinction” of the UNESCO Asia-Pacific Awards for Cultural Heritage Conservation in 2015.
