《宋书·志·卷三十一》
偏安一隅，所以用瓤比喻王朝之小。到叛军攻陷石头，朝廷大军溃败，军士抄掠京城，皇帝、太子都受到凌辱。
及石头之事，六军大溃，兵人抄掠京邑，爰及二宫。
In order to gain a foothold, the dynasty was compared to a squash. When the rebel army captured Shitu, the imperial army was defeated, the soldiers looted the capital, and the emperor and the crown prince were both insulted.
