I have had my fair share of PRC gers during the "golden years" when there were so many of them in KL. The M.O. usually goes like this; meet girl in KTV, bring her home, ask her to come again next night, meet her in China, meet her frens, bye,bye. Next! Gone through 5-6 girls like wise.
Found some of them very sweet, sensitive, & naive. Of course, some are all money-faced, so it depends on your luck. I have to say, the last two girls I did spend extra money for them to go home safely when the crackdown started. But it was mini-relationships that I enjoyed, no regrets.
these days the local girls are more cocky at KTV, and its all business.
