I am not sure what you heard about Hong Kong before, but nowadays it is actually not easy to find acceptable jobs, especially if don't speak and read Chinese, have limited working experience, and expect a salary far above the level of locals.
The main exception are people who get transfered to Hong Kong and work in the upper management of multi-nationals/finance/banking. They usually get the best deals, and Chinese skills are not essential for such jobs.
I agree with the other poster who suggested to come here for a while first to look around. Also, check the various online job classifieds to get a feeling what it takes to become competitive. Most local employers post the following three minimum requirements in advertisements: University degree, work experience, fluency in Cantonese, English and Mandarin. (But not many people in Hong Kong are truly fluent in all three languages, so this requirement is quite flexible and often basic English and Mandarin skills are enough).
