Golem Dragon - Shonen Jump Vol. 8, Issue 7 promotional card

The Golden Dragon massacre was a gang-related mass shooting that took place on September 4, 1977, inside the Golden Dragon Restaurant at 822 Washington Street in Chinatown, San Francisco, California, United States. The shooting was planned and committed by members of the Joe Boys, a Chinese youth gang, who were attempting to kill leaders of the Wah Ching, a rival Chinatown gang. The attack left five people dead and 11 others injured, none of whom were gang members. Seven perpetrators were later convicted and sentenced in connection with the murders. The massacre led to the establishment of the San Francisco Police Department's Asian Gang Task Force, credited with ending gang-related violence in Chinatown by 1983. The restaurant itself closed in 2006.
