The Tongjian dawen 通鑒答問 "Answering questions to the Comprehensive Mirror" is a historical critique of Zhu Xi's 朱熹 history Tongjian gangmu 通鑒綱目. It was written by the late Song period 宋 (960-1279) scholar Wang Yinglin 王應麟 (1223-1296) who was also the author of the encyclopedia Yuhai 玉海, the Tongjian dili bushi 通鑒地理補釋, the Kunxue jiwen 困學紀聞 and his own collected works, the Shenningji 深寧集. The 5 juan "scrolls" long Tongjian dawen has been published as a appendix to the Yuhai and is actually only a draft covering the time from King Weilie 周威烈王 (r. 425-402 BCE) of the of the Zhou dynasty 周 (11th. cent.-221 BC) to Emperor Yuan 漢元帝 (r. 49-33 BCE) of the of the late Former Han dynasty 前漢 (206 BCE-8 CE), and so only corresponds to a part of Zhu Xi's Tongjian gangmu, matters of which are discussed in Wang's draft Tongjian dawen.
The Tongjian dawen is also included in the imperial collectaneum Siku quanshu 四庫全書.
