Agree with 臭臭妈妈. he was fine with his work etc. when he was in China. Then I guese it's part of the culture shock and he was so slow even resistent to adapt to new cultural contxt and then he made one after another mistakes in many things but still refuses to learn from the mistakes, I tried to mail him books,send him email (so we can calmly communicate our perspectivs instead of arguing) and introduce trusty friends to him, nothing helps. He always blames situations and looks for excuses but never look back for what I can learn from my mistakes. Then after some period of time, when a man repeats mistakes over an dover again, his confidence gradually got lost and I watched his changes with pain. No one knows him more than I do but he never listen to me or anyone, even he hear. I am so tired to be the fire fighter but struggled for what I can do else.
