《资治通鉴·齐纪·齐纪十》
这天夜里，钟玄绍没有行动，第二早晨，他到刘坦那里去问不关城门的原故。刘坦把钟玄绍留下很久，与他谈话，而秘密派遣亲兵到他家中去抄收文书。
玄绍未发，旦，诣坦问其故，坦久留与语，密遣亲兵收其家书。
That night, Zhong Xuansha did not act. The next morning, he went to Liu Tan to ask why the city gates were not closed. Liu Tan kept Zhong Xuansha for a long time, talking to him, while secretly sending his personal soldiers to his home to collect documents.
