Some random sources of inspiration.
First, “Heroes of the East”. It’s unabashedly pro-Chinese (a samurai offering his katana to a Chinese man who defeated him in a duel? nooooo), but it showcases a lot of good fights, and has a suitably light-hearted but dramatic premise.
A Chinese man marries a Japanese woman. Both are skilled fighters, and they argue about whose country’s fighting styles are better. She leaves, he writes a letter to her, but it’s taken as a challenge by her (and more importantly, her mentor and his half dozen best friends, all good fighters too). So now he’s got to beat a series of opponents, understand Japanese customs, and win his wife back. No problem.
