The movie stars a very pretty Chinese actress Qi Shu. It’s called “Jopog Manura 3” in Korean. It was produced in 2006. Here’s some more details from IMDB: “When Aryong, the daughter of a triad boss from Hong Kong is accused of killing the boss of a competing triad, she is goes into hiding in Korea. Upon arriving, she is guided by a nimble but loyal Gi-chul and his motley crew, who are assigned to protect her until her return.”
