While discussing the upcoming Irish-Italian gun deal, Jax (Charlie Hunnam) mentions that he doesn't want the job to "turn into a 44-minute shootout with 200 sheriffs." This is a reference to the North Hollywood shootout of 1997, which lasted 44 minutes and pitted a handful of heavily armed criminals against a large number of police officers.
In Chinese, "huang wú" means grown wild. The phrase is used in the idiom "huang wú rén yan" which is translated as desolate and uninhabited.
