Mimi Chu

Having lost her father at an early age, farm security guard Chan Sai Mui grew to be an outspoken and determined woman who would do her utmost to protect her home village. It is her sincerity that has won her respect from all villagers of the Leung Choi County. Sometimes she would get too enthusiastic and impulsive that she could bring about a lot of misunderstandings. Amusingly, she has mistaken the newly appointed agricultural magistrate Tse Wong Sheung (literal meaning "Thank you, Emperor") for a thief and the two of them have been bitter enemies ever since. To keep himself from any possible trouble, Sheung has been avoiding Mui intentionally.

Sup Yee Moo is a slow-paced police and her mom, Sup Yee Ma, is the villain 'Chivalrous Flying Hawk'. But Sup Yee Ma kept that identity a secret after she left the martial arts world. Sup Yee Ma would look after Sup Yee Muo because Sup Yee Muo would always run into trouble. One day, Sui Dong Lau shows up and becomes the righteous magistrate in her city, and they would work together with Si Kei Wong to solve funny mysteries.
