“高屋建瓴”语出《史记·高祖本纪》:“地势便利,其以下兵于诸侯,譬犹居高屋之上建瓴水也。”裴骃《集解》引三国如淳说:“瓴,盛水瓶也。居高屋之上而翻瓴水,言其向下之势易也。建音蹇。”《汉书·高帝纪》复用此语,唐颜师古也用上说,注音“建,音居偃反”。今人陈直却认为“建”是“建置、建砌”义,“瓴”是屋檐角上用以滴水的瓦片,所以“高屋建瓴”义为“在高高的屋顶上建砌瓦沟用以导水”。~[1]胡丽珍持类似观点而没有注意到陈直的结论。~[2] “High House built 瓴 ” language out of “Historical Records Gaozu Ji”: “topography and convenience, the following soldiers in the princes, ”瓴, water bottle also .High house above the turn 瓴 water, saying that the downward trend is also easy to build sound 蹇.“ ”Han Dynasty Gotti Ji“ reuse this language, Tang Yan Shi ancient also used On that, phonetic ”built, Yin Yan anti“. Today, Chen Zhizhen thinks that ”building“ is a ”building, building“ meaning, ”瓴“ is a roof drip tile, so Built on the roof of tall tiles to guide the water ”. ~ [1] Hu Lizhen held a similar view without noticing Chen’s conclusion. ~ [2]
