《尚书·汤誓序》载“伊尹相汤伐桀,升自陑,”其中的陑的地理位置,有安邑之西、曹县商丘之西、济宁附近三种不同的说法,但这三种说法都有问题。陑应是山地,且其位置应该与考古学中夏文化的分布范围一致。从清华简《尹至》与上博简《容成氏》看,陑应在夏都之西,即今河南偃师二里头之西,嵩山万安山脉西麓。该位置很关键,说明商汤灭夏采取迂回战术,出其不意而制胜。这对认识夏商之间史事很有裨益。 “Shang Shu Tang vow” contains “Yi Yin phase soup cut 桀, rise from 陑,” one of the 陑 geographical location, the west of Anyi, Caoxian Shangqiu west, near Jining three different versions, but All three have questions.陑 should be mountainous and its location should be consistent with the distribution of summer culture in archeology. From Tsinghua University, “Yin to” and the bamboo “Rongcheng’s” look, 陑 should be in the west of Xidu, now Yanshi, Henan Erlitou west, Songshan Mountains West Foothills. The location is critical, indicating Shangxia eliminate summer to take roundabout tactics, surprise and victory. This is very helpful for understanding the history between Xia and Shang.
