Bai Ji-Shin Chang (張維新, Chan Waisan) is the boss of a branch of the Hong Kong Triads based in Thailand. Like Revy, he is adept with wielding a pistol in each hand (Beretta 76 and AMT Hardballer), both inscribed with kanji meaning "Heavenly King" in a fashion similar to that of gun fu. Chang is far more proficient in it than Revy who in episode 11 she states that she is "not on his level yet,". It is implied that it is he who taught her this style of combat.[citation needed] It may be this prowess in combat that makes Chang the only male to whom Revy respectfully refers to as "Sir". He has deep respect for Balalaika, who annoys him by referring to him as "Babe," though their beliefs are known to collide. Their relationship is almost playful in a business sort of way, which they started after they both survived a shoot out among each other. They both have the power to join forces, but choose not to because it would make their respective lives boring. He is currently assisting Garcia Lovelace tracking down Roberta before any unnecessary casualties are made. He also comments that Rock's actions will determine the fate of not only Garcia and Roberta, but all existence in Ronapaur and grins due to Rock's "unique" ways of handling things. Unlike most criminal bosses in the town, he advocates cooperation and joint ventures to keep the status quo in Ronapaur. He has a conversation with Eda concerning "Grey Fox", the unit responsible for the death of head of the Lovelace Family. And gets irritated when Eda taunts him no to do anything "foolish" as it will be the destruction of Ronapaur at the hands of the US.
Mr. Chang is based on characters commonly played by Chow Yun Fat in films by John Woo,[citation needed] such as John Lee in Replacement Killers and especially Mark Gor in A Better Tomorrow, as both Chang and Gor are members of the Hong Kong Triad, wield dual pistols and don similar attire.
