Chaolin bitan 巢林筆談 "Brush talks from Chaolin" is a "brush-notes"-style miscellany (biji 筆記) composed during the high Qing period 清 (1644-1911) by Gong Wei 龔煒 (b. 1704), courtesy name Chaolin 巢林, style Chaolin Sanren 巢林散人, and in his later years Jixi Laomin 際熙老民. He was a native of Kunshan 崐山, Jiangsu. He had a fondness for the classical canon and history, was accomplished in poetry and prose, skilled in stringed and wind instruments, and also trained in the martial arts. Nevertheless, he repeatedly failed in the civil examinations, and further beset by recurring illness, was compelled to abandon all ambitions for an official career. In his later years his family circumstances declined and his spirits grew despondent.
