as the new emperor; he is historically known as Emperor Duanzong.

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. After Emperor Duanzong died of illness in 1278, the Song forces' morale started to dwindle and soldiers began to desert the army. Lu Xiufu brought Zhao Bing to Meiwei (??), Gangzhou (??), which is in present-day Mui Wo, Lantau Island, Hong Kong.
