I hate to admit this, but I can’t always tell the difference between Chinese and Korean.
Well, when it comes to the sexual aspect there are many differences that you learn along the way. Even more so in the AMP world.
As for the women in general.
One of the differences between the two is the way they look physically.
A large percent of Chinese women have bigger eyes compared to the Koreans, while alot of Koreans have smaller noses compared to Chinese. Telling the two apart physically is not a challenge once you get the hang of it.
So, keep going to the AMP's, and soon you wont have any problem saying “ni hao” or “annyeonghaseyo” to the right girls.
