The System of the Tang Dynasty in the Japanese Shinsei's Epigraph

The new research of Shinsei,the Japanese's Epigraph shows that he should have been an diplomat sent by Japanese government in the year 733,instead of a foreign student coming to China in the year 731,and he died not long after he arrived in Chang’an. His Epigraph has significant sample value for the system concerning foreigners taking official posts in the Tang government. Thus it provides a way to compare the titles and ranks offered to the Japanese ambassadors by the Tang China and Japan,and further makes it known the multi-national relationship in the ancient East Asia.
