Warrior season 2, episode 2 bears the title "The Chinese Connection", and this is significant for both the show and Bruce Lee's career. The series had originally been conceived by Lee, but he was unable to get it greenlit in his lifetime. Fast-forward to 2019, and Warrior would finally be brought to life on Cinemax, with Lee's own daughter Shannon Lee executive producing along with Jonathan Tropper and Justin Lin helping to bring it out of the dust bin of history.
As one might expect from a show that was originally dreamed up by Lee, Warrior makes the occasional reference or Easter egg to Bruce Lee's filmography and onscreen persona. That said, it has been very conservative in how it's gone about this, much to the show's benefit. Warrior season 2's "The Chinese Connection" is one such example, with the title tying into the events of the episode while also being a callback to the Bruce Lee movie of the same name - or, more accurately, to The Big Boss.
The Chinese Connection had been the intended title for the American release of Lee's 1971 movie The Big Boss, with the film dealing in drug trafficking and meant to play off of The French Connection. Meanwhile, the plan had also been to pluralize Fist of Fury's title into Fists of Fury, but the two titles ended up getting switched, leading The Big Boss to be released as Fists of Fury and Fist of Fury to be re-titled The Chinese Connection. This would become a tidbit of trivia for both movies over the years, while the title of the episode is an obvious reference to this, though thematically, "The Chinese Connection" and the show as a whole are much more closely related to The Big Boss.
In the context of Warrior, the episode's title refers to Ah Sahm and Young Jun, played by Andrew Koji and Jason Tobin, striking a new deal with a local crime boss to store the Hop Wei's opium shipments. The episode also takes it further with the growing tensions between the Irish and Chinese communities in San Francisco, leading to escalating violence. Concerned for the safety of her factory workers, the mayor's wife Penny Blake, played by Joanna Vanderham, approaches Ah Sahm for the Hop Wei's protection.
With Warrior using the Tong Wars of the period as its setting, it weaves a very complex web of gang violence, politics, and racism, and the crime aspect of the show is hardly a new addition. However, Warrior season 2 using "The Chinese Connection" as episode 2's title brings it closer to home from the show's beginnings with Bruce Lee and, specifically, The Big Boss. With both the movie and the show centered on criminal activity and drug running, Warrior is working in one of its subtle Easter Eggs to Lee's career.
At a glance, simply including "The Chinese Connection" as a title might seem like little more than just an off-handed reference to the American title of a Bruce Lee movie, and knowledgeable viewers might even believe it to be a Fist of Fury reference at first. Beneath the surface, it's a much more veiled nugget towards The Big Boss. With the basic plot elements that it and Warrior share, "The Chinese Connection" is an acknowledgement of this parallel between the two.
