When Chinse male is looking for a wife, he is looking for someone who can company him till old and dead. So he is usually very picky unless he find the real love -- I mean in a real love, people are blind, not caring the standards any more.
But blonds are different, they seldom want to maintain a long term relationship. So they may not be so picky, as they think they can have another chance if they don't feel good later.
Similar to shopping. When you want to buy something very expensive, such as house, you are very picky because you know you may not have chance to buy another one. But if you just go to buy some clothes, you don't care too much, because you know you can throw it away if you don't like it later.
Chinese male is better in treating marriage. Because they are more serious.
