Qiyanlu 啟顏錄

Qiyanlu 啟顏錄 "Tales to crack a smile" is an early collection of humorous stories compiled during the Sui period 隋 (581-618) by Hou Bai 侯白. It is often described as a sequel to the book Xiaolin 笑林 by the Jin-period 晉 (265-420) writer Handan Chun 邯鄲淳 (c. 132-221).

The stories are mostly derived from ancient writings of the "masters" (zi 子) or from historiographic writings, but some are also new compilations. The language of the Qiyanlu is straightforward and the stories are written in a pretty superficial way, sometimes even in an exaggerated manner. The Qiyanlu was, therefore, not among the books in wider circulation and was lost soon.

Fragments of it are nevertheless surviving and can be found in the series Xu baichuan xuehai 續百川學海 and Shuofu 說郛 as well as quotations in the encylcopaedia Taiping guangji 太平廣記. The modern scholar Wang Liqi 王利器 (1912-1998) had collected all fragments and has published them in his book Lidai xiaohua ji 歷代笑話集. Some stories date from the Tang period 唐 (618-907) and may thus have been added later.
