《诗·鄘风·君子偕老》“委委佗佗”的意思，自毛《传》以下，各有解释。关于“委委佗佗”四字该如何读，戴君仁是采取了传统的“重言”读法作“委委佗佗”。如果就金文、战国简牍中常见的“合文”或“重文”符号使用情况来看，先秦时候的《诗经》文本“委委佗佗”可写作“委＝佗＝”。于省吾即从“新证”的方法入手，采取“合文”的读法，读为“委佗委佗”，安大简的整理者从之。从“联绵字、词”的角度来看，当以戴君仁之读为正诂，“委委佗佗”指的是“褘衣”上“宛曲而长”的山河图案。

The explanations of “Wěi Wěi Tuó Tuó” from the poem “Growing old together with the gentleman” in The Book of Songs have varied from each other sinceMao’s Commentary.How to read “Wěi Wěi Tuó Tuó”? DAI Jun-ren uses traditional “repetition” pronunciation to read “Wěi Wěi Tuó Tuó”. From the angle of Chinese bronze inscriptions and bamboo slips, “Wěi Wěi Tuó Tuó” can be written as “Wěi = Tuó =”, if the characters have the same pronunciations. YU Sheng-wu uses “new evidences” and regards them as “compound words”, so he reads them as “Wěi Tuó Wěi Tuó”. The bamboo slips scholars in Anhui University follow YU. From the view of “consecutive characters and words”, the statement of DAI is right. “Wěi Wěi Tuó Tuó” means the bending and long pattern of mountains and rivers on the “Gown of the Queen”.
