回复：嘿嘿，请问哪一个在毕业时没抄过，这个不是关键。中国传统

the fact that many people plagiarized does not make plagiarism a right thing to do. If he could simply take other person's paper and submit it as if he himself wrote it, what else can't he do? He might as well take other people's money and properties and make them his own. Just because most government officials in China are corrupt, it does not make corruption a legal thing to do. "嘿嘿，请问哪一个在毕业时没抄过，这个不是关键。中国传统". I question your ability to think logically.
