I was with one for about a decade and have a kid with her -mainland Chinese. She had been living in the US since 2008 and had fluent near-accent free English, perfect right?
At least as far as China is concerned, it is not worth it guys, even when they deeply love you they put you through pure pure Hell
The relationship with her was demand and command in addition to passionate love and if she didn't get what she wanted or her way she would through tantrums and give the silent treatment for days, this carried on and got worse with her aging and into our marriage
Foreign women also eventually start spouting a lot of the brainwash nonsense women are bombarded with here too, even Chinese
Of course she was secretive and shady with money, discovered after we were married she was giving her rich parents about a grand a month for no apparent reason and didn't mention it and just told me it was my problem when I asked her about it
Japan maybe, but China and other places don't even go there guys
