Abstract: TA contrast of four Chinese translations of Trims′ikāvijaptimātratāsiddhi and semantic analysis of vijāna, vijapti and vijaptimātratā can discover that Xuan Zang’s translating vijaptimātratā into “唯识” is well considerable, not to say the socalled “mistaken translation” causing the “mistaken region” in research for the field for thousands of years.

Key words: vijaptimātra, Xuan Zang, vijānamātra
