Don't do it. I married a china girl and my life is a living hell. All they do is argue with you and spend your money. I should have listened to people who warned me about them. They are spoiled and never admit they are wrong. You have been warned.
I think marriage is nothing with the nationality. What really counts is that you love each other. I have to admit that China has many material girls. But other countries have too. I think true love can go beyond the cultural differences. I hope you can find your true love.
