《资治通鉴·晋纪·晋纪三十九》
司马姚禹暗地里与东晋的檀道济勾结、通谋，主簿阎恢、杨虔都是姚禹的党羽，他们都非常嫉妒、厌恶赵玄，所以便对姚进言道： 殿下因为有英明勇武的谋略和能力，接受独当一面的国家重任。现在只是环城坚守，向敌人显示自己的懦弱，怎么能不受到朝廷的责备呢？ 
司马姚禹阴与檀道济通，主簿阎恢、杨虔，皆禹之党也，共嫉玄，言于洸曰： 殿下以英武之略，受任方面；今婴城示弱，得无为朝廷所责乎！ 
Sima Yao Yu secretly colluded with Tan Da of Eastern Jin, and the master book Yan Hui and Yang Qian were all Yao Yu's party members. They were all very jealous and disgusted with Zhao Xuan, so they said to Yao: Your Highness, because of your wise and brave strategy and ability, you have accepted the important responsibility of the country alone. Now just stick to the city and show your weakness to the enemy, how can you not be blamed by the court?
