The Bishu luhua 避暑錄話 "Conversations Recorded While Escaping the Heat" is a biji 筆記 "brush notes" style book written by the Northern Song period 北宋 (960-1126) author Ye Mengde 葉夢得 who has also authored the books Shilin yanyu 石林燕語 and Yanxia fangyan 巖下放言. Ye Mengde was known as a collector and was among of literati probably the one who owned the largest library in the early Southern Song period 南宋 (1127-1279). The reasons for the downfall of the Northern Song were a theme that was hotly debated among the scholars of that time. Most of saw the reforms of Wang Anshi 王安石 and the abouse of power by Cai Jing 蔡京 as the main causes for the weakness of the Song foreign politics and the destitute state of the army. Ye Mengde had been a retainer of Cai Jing, and therefore refrained from charging him guilty. In a rather objective way he explained why Cai Jing prohibited the study of history, or changed the title of princess from gongzhu 公主 to diji 帝姬, why Wang Anshi ceased to write poems and rhapsodies, and what was the intention of Su Xun 蘇洵 when he wrote the article Bianjianlun 辨奸論 "Criticism of corrupt (officials)". The 2 juan "scrolls" long Bishu luhua includes a lot of information on court history and the study of literature, and is therefore and important source on these topics.
