When it comes to Shanghai in the 2th century, we have to mention green gang, its biggest underworld force. Thanks to the painstaking efforts of its most powerful boss, Du Yuesheng, green gang's strength has reached its peak. Du Yuesheng has also become a business card of Shanghai Beach.

Du Yuesheng was born in poverty and became an orphan at the age of four. He grew up under the care of his stepmother and uncle. At the age of 14, he came to Shanghai alone from Suzhou to work hard and became a waiter in a fruit shop. Later, he joined green gang to worship Huang Jinrong as his eldest brother. Because of his flexible mind, capable work and excellent popularity, he won the favor and esteem of the Huang Jinrong couple and began to emerge. Sanxin Company, founded by Du Yuesheng in 1925, began to monopolize the opium business of the French Concession generation. Du Yuesheng is a brave man, humorous, and good at making friends with heroes from all sides. Even the warlords around him are his sworn brothers, making his power soar and becoming the first person in Shanghai.

Du Yuesheng has more than 1, brothers under his command, and even the police and the army in Shanghai dare not provoke him. His influence has penetrated into every major industry field in Shanghai, and the white gangsters can eat it all. As long as he stomps his feet, the beach will tremble. Du Yuesheng's influence was so great that some celebrities of the Republic of China turned to him. For example, Yang Du, the first think tank when Yuan Shikai proclaimed himself emperor, and Li Yuanhong, the retired president of the Republic of China, were all distinguished guests of Du Yuesheng. After Li Yuanhong arrived in Shanghai, Du Yuesheng gave a villa where he lived to Li Yuanhong, and Li Yuanhong lived here for three months. When he left, he left a couplet for Du Yuesheng, with 3, guests in Chunshen and 5 feet south of Komori. Even Li Yuanhong thought it was no exaggeration to call Du Yuesheng the local tyrant. The trivial matters on the beach are not as uneven as those in Du Yuesheng, ranging from street fights to the division of interests of various political and military power groups. Du Yuesheng should be invited to come out and adjust. Du Yuesheng said a word, but it was a word, hit the floor.

When Du Yuesheng was in the greatest power, he opened many banks in Shanghai. Regarding the specific operating conditions of the banks, he ignored them and only asked them to pay him the benefits when they were due. The benefits were comparable to sky-high prices. Under the exploitation of Du Yuesheng, one of these banks survived, namely Zhonghui Bank. When Kong Xiangxi presided over the reform of legal tender in Shanghai, he told Hess that Du Yuesheng must be invited to join the currency reserve board as a consultant. Hess, however, thinks that Du Yuesheng is just a triad society, and the establishment of a currency reserve board has nothing to do with Du Yuesheng, but Kong Xiangxi feels that it is important, and it cannot be carried out without Du Yuesheng's consent. Finally, Du Yuesheng was brought in. However, in this currency reform, Du Yuesheng lost more than 2, US dollars. Du Yuesheng claimed compensation from Kong Xiangxi, but it was rejected by Kong Xiangxi. Du Yuesheng sent these men to drag a coffin to the door of Kong Xiangxi's house that night, and there was a bloody head of a chicken in the coffin. The forces of the national government represented by Kong Xiangxi had to bow to Du Yuesheng and promised reparations.
