Definitely not true. Even Hongkies have problem with PRCs.

those are PRC not local HK-ian

local HK ade class and kutuk PRC kaw kawwwww

That one not really. There are some difference. Generally at least HK people do queue up, but unfortunately the vast majority of PRCs I observed have the habit of cutting queues whether when in taking public transport, food line, airport etc. I have also been personally pushed around by PRCs trying to make their way into a crowded shop. At least Hongkies do not behave in this manner. Some Hongkies can be loud (so are Malaysians) but generally the locals/ people in bus, train, on the street etc do not speak as loud as most PRCs do (based on personal observation and encounter).
