To sort out paperwork with my partner so we can leave China...
I wish you good luck abroad with her (or him. Just adding the male gender here because I've got an impression you are interested in males' looks and some transgender people like Chris-chan. We welcome here the gaycels, gays and the other LGBT people. Feel comfortable here and share with us everything you want to. It will be interesting to know if you guys will have same-sex marriage in your developed country.) As you said China is a developing country. Here we haven't same-sex marriages. But in the developed countries there are same-sex marriages. And if it is your case, good luck!
But, listen. A piece of mind from me. It's not important if your partner is a she-partner or a he-partner, the important is that she or he is a Chinese person. Many of us (汉族,少数民族 or 外国人raised in China or lived here for a long time) develop romantic idealization of the West. As someone said, you can expect that your Chinese partner may get very disappointed when you guys arrive there. All those school gunshots, skinheads on the streets, drunken bikers, angry black men, thugs, soccer hooliganism, speedy drivers on drugs, unstable incels and other developed states' problems can make your Chinese partner to rethink her or his residing with you there. And on top of that your culture background surely will cause you problems too. You'll need a ton of good luck. So I am here to wish it to you~~
