Emperor Duanzong of Song, born Zhao Shi on July 10, 1268, ascended to the throne on June 14, 1276, during a tumultuous period in Chinese history. As the seventeenth emperor of the Song dynasty and the eighth emperor of the Southern Song dynasty, he was the fifth son of Emperor Duzong and the elder brother of Emperor Gong, his immediate predecessor.
Following the surrender of Emperor Gong and Grand Dowager Xie to the Yuan dynasty in 1276, after the fall of Lin'an, Zhao Shi and his brother Zhao Bing fled south to Fujian, where the new Song capital was established. His reign, marked by the era name 'Jingyan,' was short-lived as the Yuan forces advanced, breaching the last lines of defense of the Song dynasty in early 1278.
In a desperate bid for survival, Zhao Shi, accompanied by loyal ministers such as Lu Xiufu and Zhang Shijie, attempted to escape to Guangdong Province. During this perilous journey in March 1278, a hurricane struck, causing him to fall from a boat and nearly drown. He found temporary refuge in Hong Kong, then a modest fishing village, but his health deteriorated, leading to his death in Gangzhou a few months later.
Emperor Duanzong's legacy is commemorated by the historical relic Sung Wong Toi in present-day Hong Kong's Kowloon City, which marks his escape route. His remains are interred in the Yongfu Mausoleum, though the exact location of his tomb remains undiscovered.
