On 4 February 1276, the Song capital, Lin'an (臨安; present-day Hangzhou), was conquered by forces of the Mongol-led Yuan regime commanded by the general Bayan.

The Mongol general Bayan was bent on eliminating the threat posed by Song remnants, so he led his troops in pursuit and attacked southern China.

Lu Xiufu brought Zhao Bing to Meiwei (梅蔚), Gangzhou (碙州), which is in present-day Mui Wo, Lantau Island, Hong Kong.

On 19 March 1279, after realising all was lost, Lu Xiufu carried the seven-year-old Emperor Zhao Bing to a cliff, where they committed suicide by throwing themselves into the sea.

[2] The grave was rediscovered in the 1960s, and despite the identity of the body interred within not being authenticated, in 1984 a joint Hong Kong-Shenzhen effort was made to restore and expand the modest gravesite.

[3] According to the locals at the Guangdong Province,[4] prior to the final battle with the Yuan forces at Yamen, Zhao Bing and the Song remnants sought shelter in a monastery at Chaozhou.
