hi just want to ask in how to get in to rosedale hotel from HK airport?

You should refer to the rosedale hotel kowloon. Well, take bus E21 at Airport (Ground Transportation Centre), and get off at Ming Kei College, Cherry Street. After arriving, walk to your hotel directly.

Or you can take airport express to Tsing Yi Station. Then transfer to Tung Chung Line to Olympic Station, Exit C5. After arriving, walk to the hotel directly.
