TS, have u been to Shanghai, Hong Kong or Macau?
In China, the first world and the third world people are living
together.
The rich people in China are extremely wealthy.
Have you been to Japan's Tokyo where they are lots of PRCs who
speak fluent japanese?To add on, have you been to places in Europe
such as England, Spain or Italy where the PRCs speak fluent
language of the locals?
How many PRCs would actually want to settle down in
Singapore?
PRCs who have lived in the cities behave differently from those
who have never ever been to a big city in China.
Source: my neighbour's a rich PRC Shanghai girl. I went to
Shanghai and Hong Kong with her and my wife as well. She spent
$15000 Singapore dollars a night consecutively for 5 nights on
alcohol.
It would actually be cheaper to travel to other parts of China
via plane or train. She insisted on driving. A trip that would cost
approximately $700 SGD by flight for 3 persons for 3 hours cost
$1200 SGD and more than 10 hours. 
Now for the recent news:
Singapore is ranked 9th in the most expensive city to
live in. Hong Kong, Shanghai and Beijing are ranked
6th, 7th and 8th respectively. Singapore's global
rank in the most expensive city is 67 while that
of Hong Kong, Shanghai and Beijing are 34,
46, 55 respectively.

You're actually contemplating on marrying a girl who comes from
a country dubbed world's 2nd largest economy after the USA amid the
large difference in income gap between the different social levels
in China. You need to make a comparison between the PRCs girls in
Japan, USA, England and Singapore before you make a deicision.
