此事是有點怪。不過我覺得好像沒什麽隱晦的政治原因，反而可能是某種"政治正確"帶來的滑稽現像。

That is, every and each society has its ridiculous "correctness". In US it is related to racism as a consequence of that bitter part of its history. In China, it can be some ethical principles that bear syndromes of an old past history complicated with revolutions of contradicting foreign doctrines. The society just doesn't know how to assert its correctness of values yet.

Towards our motherland, I think we should stay cool and positive.
