This article is written to counter Chu Guo Qing's paper ”The Movement of Naming Japan 'Fu Sang' Began in Tang Dynasty” and the viewpoint Charlotte Von Verschuer addressing in his essay that the situation of Tonghaiguan and Ribenguan coexisting in the term ”Fu Sang” appeared earlier in China than in Japan. I kept searching relative data in the classics of China and Japan to carry out the work of controverting in order to make clear the fact that Chinese in Tang Dynasty never named Japan Fu Sang and they gave this name to Silla instead. The people who called Japan Fu Sang were Japanese themselves. Chinese just followed them after this established practice had prevailed in Japan and it happened in Bei Song Dynasty. Even so, after Ming Dynasty did the Chinese people then gradually form the common view of naming Japan Fu Sang.
