As early as in the Qin dynasty (221 BCE – 206 BCE), Kowloon City was famous for its pearl production. During the Song dynasty (960–1279), Kowloon City was a part of Kwun Fu Cheung (), which was a part of salt yard governed by Chinese officials. During the late Song Dynasty, two young emperors Zhao Bing and Duanzong sought refuge at current day Kowloon City, roughly at present day Sung Wong Toi Garden to escape from the growing Mongol Army. There are also historic relics and a temple which dates back to 800 years ago.
