The United States and China share a long history of cooperation. Now China has the largest International students amount around the US. However, because most of the International students are busy studying, or because they are the unprivileged losers, so few of them has a girlfriend/boyfriend. What's more, without a American girlfriend/boyfriend, they cannot get involved in the local community perfectly. THEY STILL FEEL THEY DON'T BELONG TO IT HERE.
Giving each diaosi, in other words, the unprivileged loser a American girlfriend/boyfriend can help them to build their confidence to beat those privileged winners (gay shy fool), to create successful careers , to assimilate into American culture better as well as to boost the weak American economics faster.
So, vote for yourself, diaosi!
