Xu Shen
A number of Xu Shen's character analyses are erroneous, as the seal script differs considerably from the older bronzeware script and the even older oracle bone script, both of which were unknown at the time, also to Xu Shen. Karlgren, for example, disputes Xu Shen's interpretation of 巠 (jing) as depicting a subterranean water channel. Referring to the bronze script, he proposes a reading linked to weaving. Furthermore, Xu Shen does not account for historical phonological change that between the earliest days of Chinese writing and his own era. This results in inaccurate sound analyses.
