Is Hong Kong a country or a city?

Neither really.

It's a special administrative region of China.

China is a strange place. You can't live or get medical care in the major cities unless you have a special city residence permit (kind of like a passport). Only the cities receive good medical care.

...but they get their own passports, different than PRC ones.

So if you are a "permanent resident" of the HK SAR, you are entitled to an SAR passport. 143 countries visa-free, as opposed to a PRC passport, which is like hanging a sign around your neck at immigration saying, "Please Detain Me".

I thought it was an island.

It is a state of China.

There are many female PRC residents who are very worth "detaining."

It's not a place but rather a state of mind. They're all commies now.....
