Tai A Chau is home for both farmers and fishermen who use the island as a permanent harbor for their small floating homes. The daily routines of Mr. Wong, a fisherman, and Mr. Ng, a farmer, are representative of their respective problems of survival, mutual dependence, and hopes for the future. Island in the China Sea is the introductory film in the China Coast series of Faces of Change. It provides a broad overview of the rural societies of both the island farmer and the boat people who harbor here. It traces the lifestyle of agricultural and fishing families, juxtaposing their daily activities and their tacit interaction. The symbiosis is in delicate balance, however, since ideas of class and caste set the two groups apart. Island farmers have traditionally regarded boat people as inferior.
