《太平广记·卷一百四十一·征应七》
曾经与皇上对诗，让仆射颜师伯执笔，庆之随口吟出： 微小的生命多么幸运，能赶这样的好时代而命运昌盛，现在老了不中用了，回到南山冈种地吧。
尝对上为诗，令仆射颜师伯执笔，庆之口占曰： 微生值多幸。 得逢时运昌，衰朽筋骨尽，徒步还南冈。
 Once, he composed poems with the Emperor and asked his secretary Yan Shibo to write them down. Qingzhi said impromptu: Tiny lives are lucky to be born in this wonderful time. Now too old and useless, let me retire to Nanshangang to farm.
