You're white, for most Chinese families that is very good, better than owning an apartment. Plus you're from Canada, that is automatic opportunity for their daughter and the rest of her family. Given Canada's preference for uniting families in immigration policy if you marry her then the better part of her immediate family gets in much easier.

Some of my friends (guys no less) get paid to go to clubs in China just because the owner wants to associate it as a place white people go.
