《姜元澤家藏契約文書》是瞭解清代中後期苗族家庭經濟生活的一面鏡子,也是洞悉清代中後期苗族家庭漢語言使用風貌的一扇天窗。該書的整理出版具有重要的資料價值。但由於整理者對文書中某些俗字的情況失察,其釋讀還存在一些可商榷之處,本文選擇其中五則予以訂正。 “Jiang Yu-lao Tibetan Contract Instrument” is a mirror to understand the economic life of the Miao family in the late Qing Dynasty, but also a skylight insight into the use of Chinese language Miao family in the late Qing Dynasty. The book finishing publishing has important information value. However, due to the lack of inspection by the trimmer of some vulgar characters in the document, there are still some debates on its interpretation. The article selects five of them to be revised.
