Dating

Dating with people who are from different cultures is somehow sometimes really challenging. I talked with lots of western guys who are dating with Chinese women. They found it interesting, weird or complex. Later on, they may want an understanding lady who is on the same level with them. But I guess that is the culture shock which no one can actually overcome.
I stayed in the US for 2 years and totally enjoyed the culture there, and I kind of think myself to be Americanized. Independent, spontaneous, I gave myself this these kinds of labels.After dating some western guys, I learned a lot and totally get along with them. The more I get to know them, the harder I found find it to understand them. What are they looking for? Or what am I looking for? People may think the mainly difference we have is the attitude towards sex. But actually it's not, what we don't have in common is the idea of the value of life, and the attitude of toward life, work and family. Is it really hard to fall in love with people from different cultures?
