I always beleive in helping people in need, but also must be
mindful who you are helping and the risk you may get yourself
into.
For example, if your friend ask you be a guarantor for a loan,
don't do that unless you are prepared to pay off the loan if your
friend default on the payment. I once turn down a friend who asked
me to be his guarantor. After that, he never talk to me anymore.
Can't blame him but what to do, I have a family to feed too.
There is a Chinese saying.. (Direct translation) "Know a person,
know his face, but don't know his heart..."
