新舊兩譯 The new 新譯 and old 舊譯 translations of the Buddhist canon into Chinese. Those works translated prior to Xuanzang 玄奘 are considered old, and the those from the time of Xuanzang are new. Xuanzang established many new standard terms for translation. For example, prior to Xuanzang, the term for "sentient being" (sattva) was translated as 衆生, and afterwards as 有情.

Old and new methods of or terms in translation, the old before the new with Xuanzang.
