I've read add'l post you put on another forum:

"1）今后不是份内的事，一定要少做。工作越多，错误越多。当时，我是急于表现，希望老板能给办绿卡."

---True,better do nothing other than socializing.

"2）同事就是同事，不会成为朋友。有了自身利益，不会给我说话的."

---Agree,they could turn around to be your enemy one day

"3）找工作时要问清为什么这个职位有空缺。我到了才知道，我的位置在过去7年中，已经换了14个人了。这样的公司不能去."

---That's why I always ask how many people in theis Dept,doing the same job,the nationality and seniority during the interview.Beside,after you join the company,those idiots will tell you that how many people have been in your position & how long.Funny...eh...when the number is too high,say no to the position.


***This is Bullshit

Take care buddy,let it go.
