China Rose - George C. Scott (1983) - General Post Office, Central

Further to my suspicion that the film company couldn't film at the HK-Macau ferry terminal (for whatever reason), the scene where Scott and MacGraw are supposedly disembarking from the ferry was actually filmed next to the Post Office on Connaught Place. Of course, it could be that at the time this was the point for disembarking due to construction of Shun Tak? I hope someone in the know can relieve me of my ignorance.
