At the end of each volume or each case of Jiaxing Tripitaka, a large number of phonetic explanation characters are attached. These characters are collectively referred to as the Suihan Yinshi. They use “Yinshi” and “Yinqie” and so on as their documentary identifiers, and are scattered at the end of each volume or at the end of the entire Buddhist scripture. The layout generally follows the pattern of Xuan Ying’s Yinyi: First, the character to be annotated is extracted, and then its pronunciation is noted and its meaning is explained. The catalog of characters and their annotations in the Suihan Yinshi of Jiaxing Tripitaka are rather complex, and the methods of phonetic notation are diverse. Overall, the Suihan Yinshi of Jiaxing Tripitaka are characterized by complex annotation materials, diverse base texts, and rich phonetic notation levels.
