The Ah Peks usually is a batchelor, or a widower, usually with
no family.
After 40-50 years of toiling as a blue collar worker, labourer, and
saving, they now have money. Unless you are related to them, what
they do is their business.
The PRC Girls, for them its economics.
If they have a stable income, they won't latch themselves to these
Ah Peks.
In the meantime, this will do. For they have to get by here in
Singapore, until they get the job that they fantasied about.
Bottomline, these Ah Peks and PRC Girls are doing what we all are
doing: Keeping away misery.
