My Kingdom is a 2011 Chinese wuxia film directed by Xiaosong Gao and starring Wu Chun, Han Geng, Barbie Hsu, and Louis Liu. The film tells the story of two orphaned brothers, Guan Yilong (played by Wu Chun) and Erkui (played by Han Geng), who were taken in by opera star Master Yu after the mass execution of their clan. Growing up, the two brothers become skilled performers and martial artists under Master Yu's tutelage.
However, their thirst for revenge against the Qing Dynasty and the Prince Regent for the death of the Meng clan still burns inside them. When they hear that the coveted golden "The Mightiest Warrior" plaque, which Master Yu had won but subsequently lost in a duel with his archrival Master Yue (played by Louis Liu), is going to be put on display in Shanghai, the brothers see it as an opportunity to exact revenge and reclaim what they believe is rightfully theirs.
Upon arriving in Shanghai, the brothers encounter Master Yue's opera troupe and easily defeat them, causing Master Yue to flee. Guan Yilong and Erkui take over the troupe and use their talents to gain money and influence in the city, with the ultimate goal of avenging their clan and bringing down the Qing Dynasty.
Throughout the film, there are several sub-plots involving love interests for both brothers, as well as a power struggle between local warlords and the Qing Dynasty. The film is notable for its impressive fight scenes, choreographed by legendary martial artist and actor Sammo Hung, as well as its incorporation of opera into the story. The music of My Kingdom features both traditional Chinese opera and modern pop music, reflecting the cultural clash between old and new China.
