Mangrove ecosystems are one of the four most productive tropical coastal marine habitats. In this episode of Tides of Change, CGTN reporters Tao Yuan and Li Jianhua visit a mangrove forest in Fangchenggang in south China's Guangxi Zhuang Autonomous Region. The forest is home to over 110 species of mangroves and is of global significance as a flyway for international migratory birds and fish habitat. Join CGTN to explore the unique plants and marine animals in the Beilun Estuary National Nature Reserve.
