Humpmedumpme ; in case you do not know ( but my guess is that you do ) Hong Kong ATC ( and CAA) are not operating and trained the same way as mainland PRC and they do not follow the same rules.
The generic R/T exchange you posted is unfortunately reflecting the current sate of affairs in the PRC , where the whole airspace is military . Chinese controllers ,like everywhere else on the globe , have to follow the rules imposed on them , and are as much frustrated as you do having to say " negative " all the time.
I have read t recently that there are intentions to take some airspace away from the military to extend the civil areas of responsibilities, but these are definitively political decisions which are not in the hands of ATC .
