The movie expresses the difference of culture and discrimination to some extent. But whatever the discrepancy is, people in this world still have something in common, in front of the authority and prejudice, we can also move everybody and withdraw their preconceptions, they can be influenced by our love. In fact, love has no national boundaries. What's more, I felt angry when I saw some situations, I even thought Americans are meddling, but finally I just wanna say, as long as you make everything clear, Americans are reasonable.
