In reply the pilgrim states that Chi-na (支那) that is, Chin was the designation of a former dynasty in his native land, and that Ta T'ang denoted the present dynasty; that the sovereign then reigning, T'ai Tsung, had been styled Ch'in-wang before he came to the throne, the title Emperor (T'ien-tzŭ) having been given to him on his accession. He then adds a compendious description of Ch'in-wang as Prince and Emperor.
