In the early 1920s, the Japanese writer Tsukaze Muramatsu, who visited Shanghai for the fourth time, exaggeratedly wrote in the book "Magic City": "If you walk on the street, you can be regarded as a thief if you are a man, and a prostitute if you are a woman. Let's go." This kind of remark can't be said nonsense today, it is a serious insult to China. The Japanese writer Akutagawa Ryunosuke, who came to China five years after the Revolution of 1911, writes reports every day and sends them back to Japan for publication. He ate fried dough sticks, watched "New Youth", and walked the streets and alleys of Shanghai, a city more prosperous than Tokyo. He found that most people in Shanghai had the habit of "calling a bureau" (recruiting prostitutes).
On the bureau tickets of Yaxu Garden, "the words 'Don't forget the national humiliation' are printed in the corner to encourage anti-Japanese arrogance." It is Chinese characteristics: when recruiting prostitutes, one does not forget to be patriotic, and when one is patriotic, one does not forget to recruit prostitutes. He saw someone buying and selling children on the street, and the photo retouching other party told him: "The smaller one is three yuan, the older one is five yuan, and if I want a bigger child, the girl from that family is fifteen years old, and I will take it away for fifty yuan. He met with Li Renjie (Li Hanjun), a radical intellectual who had studied at the University of Tokyo, and talked about his views on current affairs. Li said, "In modern China, there is no public opinion, and without public opinion, revolution will not take place."
Four years later, the National Congress of the Communist Party of China Li Renjie held a secret meeting at his house, and was transferred to a cruise ship in Jiaxing Nanhu after attracting the attention of the patrol room. One of the participants was Mao Zedong, the "hero" who would change Shanghai and China in the future. Li Renjie was arrested and killed in Wuhan in 1927 by the generals of the Guangxi clan. Shanghai, the most capitalist city, is the cradle of the Chinese Communist Party. This contradictory dual identity still haunts Shanghai to this day.
