According to historical records, when the child emperors Zhao Shi and Zhao Bing of the Song dynasty were fleeing south when the Song Empire was gradually being conquered by the Mongol Empire in the late 13th century, they took refuge at the Sacred Hill along the seashore. Zhao Shi died of illness in Hong Kong, while Zhao Bing died when the Song loyalist Lu Xiufu put him on his shoulders and jumped off a cliff following the defeat of Song by the Mongols at the naval Battle of Yamen.
