Chinatown tong wars in San Francisco

This article was talking about the tong wars in San Francisco presented me how brutal the conflicts were among Chinese immigrants back in the 19th century. It was ridiculous that how woman became the source of a conflict and ended with deaths and casualties. On the other hand, the Chinese Squad, employed by the San Francisco government, were no different than the tong members. They often break into tong headquarters and destroy the furniture inside. It was their way to scare tong members away from battling. However, American tongs surprisingly worked together in supporting Dr. Sun Yatsen for overthrowing the Qing Dynasty (1644-1911). It was probably because they hated Qing Dynasty than anybody in China. The tongs in America consisted with people from Hongmen, who claimed to restore the previous Ming Dynasty (1368-1644) in China, and some remnants of Taiping Rebellion (1851-1872).
