Alternative name for Hong Kong 香港 Just as Mainland China can be referred to as 中国, 大陆 or 内地, 

I was wondering whether Hong Kong has any alternative names (official or just as slang).

In English, we refer to Hong Kong in slang as 'the concrete jungle' or more officially, 'Pearl of the Orient'.

So I was wondering if there are any Chinese names other than 'fragrant harbor'.
