Bai Niao Cangji's related evaluation.

Wada Sei, a master of Bai Niao Cangji and a famous oriental historian, once said: "The characteristics of Dr. Bai Niao's research methods always adopt western methods. Japanese scholars have always been influenced by Sinology, and most of them can't get rid of the heavy pressure of China people's way of thinking. However, Dr. Bai Niao can use the latest scientific methods in the West to seek new explanations for old problems with brand-new eyes ... learn from geography, linguistics, religion, folklore and other knowledge to solve various big problems such as history of manchu, geography, race, nationality, language, customs, ideology and culture. " Generally speaking, Bai Niao thinks that he is the first Japanese and the first person in East Asia who has the rule of law in the West, or he has turned the history of East Asia into a modern, empirical and scientific one.
