I have been flocked together with our chinese people. During the job interviews, my communication skills are weak obviously. 
Some friends laughed me that you guys always stay in Chinese church and speak Chinese all day.Therefore your English ability definitely is weak than others.
I know that they maybe right and I do want to improve my English. However I don't have sufficient time to do it because we have to serve people. Eventually it is hard to get a job offer.
I feel that it is reasonable at some extent; I feel bad because I have not gotten a job offer.
I want to get angry but no proper place.
Can you image the situation such as a might lion is locked in a small cage?
Thanks for your correction.
