Just read about this post by a PRC undergrad in our local university and that certainly was a very unpleasant remark he had posted.

2 reasons I could analyse from his response in this manner - either he is just irritated at the moment, or he is simply rude, ungrateful that he has a chance to study here in Singapore.  Another question that the leaders might have to answer to the public, is, are they going to spend so much for such qualities of "talents"?

Personally I think he owes the nation who gave him this chance to study here a very big apology.
