At the start of the 20th century, years of growing gang activity finally erupted into a war between two prominent Chinese gangs, the Hip Sing Tong and the On Leong Tong. The first major shooting occurred in 1905 when several Hip Sing Tong members pulled pistols and shot four On Leong Tong members, killing two of them, at the Chinese Theater. This would be the start of a long and bloody war. In 1909, the war escalated further when a woman, Bow Kum, was murdered by a Hip Sing assassin because she was believed to be the property of another man. After the murder of Bow Kum, violence ramped up to an unprecedented level in Chinatown, and Doyers Street became the center of that violence because of its unique curve and underground tunnels which made fleeing after an attack much easier.
Peace came to Doyers Street in 1913 after four years of intense war. Though violence did not end completely, the two gangs could no longer justify losing money because patrons were too afraid to enter the businesses on Doyers Street for fear of death. However, violence erupted again in the late 1980s when the Flying Dragons, who were associated with the Hip Sing Tong, went to war against the BTK, a Vietnamese gang that arose after the Vietnam War. Violence from these two gangs flooded Doyers Street until 1994 when cops started cracking down on illegal activity in Chinatown. Today, Doyers Street is more of a tourist attraction than a war zone, but the Street's bloody past is still remembered.
