I get the feeling thet they either will adopt a baby or make one using a how is it called ...

adopting a child as gay couple is very easy in some country like vietnam, taiwan or thailand. I don't think a country as conservative as China would allow same sex couple to adopt a child but you can always adopt a kid as a single parent very easily in most of Asian countries. I think they will probably using the buy egg and ask for a surrogate is much more easier.
