On the wooden slabs unearthed from the tomb of Guojianao (formerly, Guo) in the period of Sun Wu of the Three Kingdoms, there is a sentence with the words “針囊一枚, 白糸一 , 青糸一”. Past scholars interpreted the three characters “ ” ,“ ” and “ ” as the word “縱 (zong)” , which means “silk thread”, and “ ” ,“ ” as the word “㢧 (卷, juan, volume)”, which is a measure word. This study verifies that the word “ ” is “ ”, and “ ”, “ ” are “ ”, which are all variants of the word “線 (xian, line)”. This was achieved by changing the phonetic note. The measure word “ ”, “ ” used for weighing silk thread should be a variant form of the word “斤 (jin)”, which is similar to the writing of “ (jin)” or “ (jin)” in the Pan’s clothing list of the Eastern Jin Dynasty.
