水至清则无鱼。社会吗，活的就是交际。关键是几千年了，咱中国关系，人情，无不是如此。就个人而言，都有爱憎之分，何况于咱们的传统，文化中的一部分。孔子还杀了少正卯。走关系，人情，在咱中国能说啥，谁也除不了的，大家习惯了。重点在于贪污，比较黑的黑幕，则是有可能改正的，需要长期努力。千年的社会风气，能怎么办，有苦自知了，唉。努力往上走吧。

Thank you for the insight.

Yes, I heard about it before.
That's why I choose my former university.

Anyone will feel helpless facing such challenge.
I believe pre-exam preparation is vital, you'd better find out the culture there.
With passion to try luck is not a sound way.

As a candidate, you can actually talk with some professors in advance.
Their instruction will help you a lot.
Finally, I wish every candidate is able to turn his or her dream into reality.
Don't give up.
Learn lesson, apply in the next run.
Never, ever, give up...... please

绝对的公平是不存在的，唯一能做的，是成为强者，这样才不会轻易被人打到！
