Live: Hong Kong and Dongguan, a tale of two cities with shared prosperity

In 1839, Lin Zexu, a Qing-dynasty (1644-1911) official, launched the destruction of opium in south China's Guangdong Province. This act triggered the onset of the Opium War, also known as the Sino-British War. Due to this war, Hong Kong was ceded to Britain until it returned to China in 1997. CGTN's Zhao Yunfei visits the Naval Battle Museum, located in Dongguan City in Guangdong Province, to look back at this history, while fellow reporter Zhu Dan is in Hong Kong to cover the region's development since its return to China and life in the Greater Bay Area.
