Sung Wong Toi is an important historic relic in Kowloon, Hong Kong. While its remaining portion is currently located in the Sung Wong Toi Garden in Ma Tau Wai, it was originally a 45 m tall boulder standing on the top of Sacred Hill in Ma Tau Chung above Kowloon Bay.
The name Sung Wong Toi literally means Terrace of the Sung kings. The stone is believed to have been a memorial to the last two boy emperors of the Southern Song Dynasty, Zhao Shi and Zhao Bing, who temporarily lived in Hong Kong from 1277 to 1279. According to historical records, the two young Sung emperors were pursued by the Mongolian army and fled south, eventually taking refuge at the Sacred Hill along the seashore.
Zhao Shi died of illness in Hong Kong, while Zhao Bing died when a retainer put him on his shoulders and jumped off a cliff following the naval defeat of the Sung Dynasty by the Mongols at the Battle of Yamen. After the Sung Dynasty was overthrown by the Mongol army in 1279 AD, local residents inscribed the words "Sung Wong Toi" on this large rock that was on the Sacred Hill at that time.
