I would definitely leave if I was in the same situation

I am sure you can find something better. Working for the right boss/manager is very important...from what you mentioned here, you have a very BAD BAD BAD boss.

"其一是老板工作没有什么章法，常常改主意，一改大家就得顺着一起改，弄得大家都很累，我作为team led也很头疼，已有问题老板就兴师问罪，但是很少有人说''you are the biggest problem". 我们这个组比别的组累很多，工作压力大，虽然成绩是有，都是在高压状态下完成的，不是长久之计"
