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.
