How did the word "Zhongshan" come from? It turns out that Mr. Sun went into exile in Japan from London on August 1897. One day, he and Japanese Hirayama visited Inukai Tsuyoshi together. On his way home, he wanted to stay at the nearby Duihe Hotel. The hotel owner asked that all the names should be recorded in the register. Hirayama Zhouyi thought of the name of Zhongshan Hou, so he wrote the word "Zhongshan" to Mr. Sun as his Japanese surname to avoid exposure. Firewood is not just an ordinary person. In the late Qing Dynasty and the early Republic of China, Sun Yat-sen's fame spread all over the country and is still deeply rooted in people's hearts. However, Japanese people are used to calling Mr. Sun, while Europeans and Americans are used to calling Mr. Sun.
