actually, I am very curious how PLA HK Garrison utilities this builiding.
The brit and the west were doing a lot intelligent collection work in Hong Kong against the commie block pre 1997. On the other hand, the PLA HK Garrison is more of a symbolic one,how much office space for paper work could they utilizes.
One would suggest , they could do intel. collection work for any anti PRC government at this building, but one with the least military sense would know they could be better off doing than on the other side of the shenzhen river.
