Zhou Xing said,"It's quite easy!Pick a big porcelain jug and toast it with charcoal,then put the prisoner in it,won't he confess?" 本文出自《资治通鉴·唐则天皇后天授二年》：“或告文昌右丞周兴与丘神绩通谋,太后命来俊臣鞫（ju1）臣与兴方推事对食,谓兴曰：‘囚多不承,当为何法?兴曰：’此甚易耳!取大瓮,以炭四周炙（zhi4）之,令囚入中,何事不承!’俊臣乃索大瓮,火围如兴法,因起谓兴臣：‘有内状推兄,请兄入此瓮.’兴惶恐叩头伏罪.” 比喻即以其人之道,还治其人之身.“请君入瓮”的故事就是由此产生的.
