One of the reasons I have left the US is to get away from the racism there. So, I do not think it would be a good idea to go a country that seems to be even more racist.Chinese women tend to be pragmatic, materialistic, and controlling. Plus men and women in China tend to be emotionally stunted unless they have been exposed to a good education and a decent social environment. The reality is most Chinese people would look down on a woman marrying a foreigner unless of course you're talking about the lower working class type people. From what I gather from the posts on here most expats seem to be dating the blue collar or lower-middle class women. I have no experience with these types but I assume there's probably less scrutiny about what they do in daily life. I imagine the family probably wouldn't like it much because they expect to be taken care of in old age and there's this rather justified belief that if their children marry a foreigner it's likely the "foreign" son or daughter in law won't give two shits about them.
For the middle/upper middle class Chinese it's definitely taboo in a lot of ways unless the foreigner in a substantial occupation like business owner, doctor, lawyer etc.. The attitude is similar to Thais in some ways which isn't surprising since the middle/upper middle class in Thailand is made up of people from a Chinese-Thai background
One good thing about the RP is that it has a lot of poor and educated people- teachers, nurses and all that. They have BAs and have completed studies of other kinds and they are just like me- and I can date them. Unlike in Thailand. Or China as you have described. I think it will not be on my list any time soon.
