"Chinese" can mean the written OR the spoken language. It can also be used to describe people who are born of this descent.

Since this series takes place in an era of HK before the late 1990s (before it is officially returned as a part of China), "Chinese" can be loosely used to mean Cantonese, since Mandarin hasn't been established as a common dialect of China yet. On the other hand, Cantonese is the predominant language of the local area. So, I think what 松哥 said is acceptable.
