Chinese Odyssey 2002 天下無雙

The Emperor is desperate for the free-spirited life of a wanderer, and tries to escape from the royal palace with his sister, the Princess. He's caught and returned to his angry mother by the royal guards, but the Princess, disguised as a man, manages to escape. Meanwhile, King Bully has returned to his hometown, where he is widely despised for his bullying ways, to run a restaurant with his tomboy sister, Phoenix. They have a very close relationship. In fact, King Bully mistakenly believes that he can read his sister's mind. When the Princess arrives in town, King Bully finds himself drawn to her, but, believing she's a man, decides that his attraction is some kind of empathy with Phoenix.
