《宋书·列传·卷五十三》
丹阳尹刘穆之权盖当时，朝廷民间人物都惟恐趋奉不及。而未和刘穆之相结交的只有谢混、谢方明、郗僧施、蔡廓四个人而已。刘穆之相当怨恨他们。
丹阳尹刘穆之权重当时，朝野辐辏，不与穆之相识者，唯有混、方明、郗僧施、蔡廓四人而已；穆之甚以为恨。
Liu Muzhi, the magistrate of Danyang, held power over the country at the time. Figures from the government and civilians were all afraid that they would not be subservient enough. Only Xie Hun, Xie Fangming, Xi Sengshi, and Cai Kuo did not associate with Liu Muzhi. Liu Muzhi resented them quite a lot.
