The Chinatowns of the 1960s and 1970s experiences a rapid influx of working-class immigrants from Hong Kong. Since their inception in the late 1960s, the Hong Kong-born immigrants and mostly unemployed though some work as waiters and busboys Wah Ching (華青) gang members began a campaign of harassment and assault of white tourists in San Francisco's Chinatown, which ultimately proved to be a predicament for the tourism-minded conservative Chinatown elite of the Chinese Consolidated Benevolent Association (the biggest problem is that the CCBA simply advocated tougher policing against the gangs rather than resolve Chinatown social inequalities at the core). In North America, Chinese American street gangs often have connections with the tongs and triads. Examples of such street gangs include the Joe Boys and Jackson Street Boys, which are named after the major street of San Francisco's Chinatown.
