China has a coastline more than 18,000 kilometers long, starting from the mouth of the Beilun River in the south and stretching northward to the mouth of the Yalu River. CGTN has launched a special program, "Tides of Change," which tracks China's ocean economy, starting from the South China Sea. Our livestream odyssey begins from Boundary Monument No. 1 from the Qing Dynasty (1644-1911) in Fangchenggang City, south China's Guangxi Zhuang Autonomous Region. #TidesofChange
