China has a coastline stretching 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
