Du this person is very smart, also very clever, du and * * * have a blood feud. 1927 4. 12 Before the tragedy, Jiang had decided to take action against * * * and informed the Shanghai hooligans. Under the oppression of Jiang's strength and prestige at that time, Du also participated in the killing of * * *. Du's post attracted the then chairman of the Shanghai trade union to the door. Because Du had a good reputation in Shanghai and was loyal to his friendship, Wang didn't doubt that he had one, so he kept the appointment generously. Unexpectedly, he was caught by green gang and buried alive. At this point, Du has forged a blood feud with * * *. During the Anti-Japanese War, Du also sponsored * * * anti-Japanese materials, but it can only be regarded as a casual acquaintance with * * * and has not been pardoned by the top. 1949 before the liberation of Shanghai, Du knew that the Kuomintang was going to die. However, his blood feud with * * * has not been resolved, and Du was extremely disappointed with Chiang, so he moved to Hong Kong to wait and see. Du also advised Huang to take refuge in Shanghai, but Huang was old and the idea of returning to his roots prevailed. Besides, * * * sent someone to persuade him to let bygones be bygones as long as he didn't make trouble, so Huang decided to stay. Seeing that Huang had made up his mind, Du fled to Hong Kong with his family (Du didn't bring much money, and Du's property basically stayed in the mainland, and Shanghai's real estate accounted for most of his property) to wait and see the development of the situation in the mainland.

Mayor Chen Yi has sent people to Hong Kong for many times to persuade Du to return to Shanghai, keeping Du's property in Shanghai untouched and promising to let bygones be bygones. Chiang also sent people to Hong Kong to persuade Du to go to Taiwan Province, but Du always pretended not to offend. Just then, a sudden thing broke the balance. Because of the people's dissatisfaction with the big gangster Huang, they asked the government to arrest and execute Huang. Because it was announced at that time, besides, Huang didn't make trouble in the new society, but in order to calm the public's anger, Huang was asked to write a critical letter and let him sweep the floor in rags at the gate of the world (Huang's property). Later, it was also revealed that two apprentices sent by Du were killed and executed by the people's government. Du has eyes and ears in Shanghai. Seeing this situation, he is even more reluctant to come back and is glad that he did not stay in Shanghai. 195 1 year, Du died in Hong Kong, leaving countless IOUs burned by him, leaving more than 100,000 dollars to many wives and children. After Du went, it was hopeless, and all Du's property in Shanghai was confiscated. Du Youyi's wife and concubine, angry with Du, returned to Shanghai with two children and suffered a lot during the Cultural Revolution. Of course, Du had passed away at that time, and there was no way to know. After Du's death, his wife was buried in Hongkong and moved to Taiwan Province Province, so Du's mausoleum remained in Taiwan Province Province.

Although Du died young, most of his children stayed in Hong Kong and overseas. Because Du paid attention to education in his early years, he had many friends and his children didn't suffer anything (except the two who came back). Most of them are well developed and talented people come forth in large numbers. As for wives and concubines, because they all have some private money, they will be more than enough for the rest of their lives. As for Du's eldest daughter, she later said that Du mistakenly handed the letter to Jiang, so she was watched by Jiang. This statement has no credibility at all. No matter how long Jiang's hand is, he can't reach Hong Kong. I believe this is just an excuse, but Du has been reluctant to go back by himself.
