Textual Research: In the Zuo Commentary (Zuozhuan), Year 16 of Duke Cheng, the text states that the Viscount of Chu climbed into a nest-carriage to observe the Jin army. The annotation says the nest-carriage was originally written as a variant form. I have checked the annotation and it does not contain this remark; I have corrected the note regarding the Explaining Graphs and Analyzing Characters (Shuowen) accordingly.
