I have been asking this question for a long time: 田刚究竟有什么＂问题＂ specifically. No one have given any factual answer so far, only speculations and imaginations.

牛相伯, whom I agree mos of the time, had a nice try: 田刚两度被北大引进，拿高工资不回国.

This accusation is highly questionable. 北大 is willing to pay Tian, and Tian happily accepts. What wrong with that? Welcome to the free market. As long as Tian does not cheat and 北大 doesn't complain, there is nothing wrong with Tian what so ever.

Lao 牛 then try again: 我们其他人呢，大多数认为田有问题. That's even more questionable. This means Tian must have 问题 because some people think so.

Tian may or may not be an angel. For any one who 认为田有问题, please come up with some verifiable facts, please!!!!!!!!!!!!!!

Why are so many people so eager to destroy someone?
