Which Peaky Blinders character is a Chinese criminal leader involved in opium smuggling?

Brilliant Chang is the Peaky Blinders character portrayed as a Chinese criminal leader involved in opium smuggling.

In the series, Chang is a Chinese opium supplier who negotiates with Thomas and Arthur Shelby during the fifth series. He becomes connected to the Shelby business through the movement of opium and other illicit cargo, placing him among the show’s international criminal contacts rather than among the Shelby family’s regular members.

The character is based on a real historical figure, also known as Brilliant Chang, who operated in London’s Chinese community and became associated with drug trafficking. Andrew Koji plays the fictionalised version in Peaky Blinders. The programme uses the historical name and criminal reputation but adapts the details for its plot.

The other choices are separate characters: Billy Grade works for the Shelby organisation, Barney Thomason is a former soldier and marksman, and Jimmy McCavern leads the Billy Boys gang.
