I am sad to hear of Mr Tian will lose his job forever.He had taught me three years before I was took out of the mountains.I still remember him carry us on his back across the river.And he has been an only teacher in the school ever since I could remember.Yet,the government want he to go home now.That’s to say,they don’t allow him to be a teacher any longer.Why?That’s unfair of all the teachers like Mr Tian.Cities have many good teachers,and few want to work in a remote mountain school.The government has once sent some teachers there,but nobody of them stayed.What will happen to the little friends there once Mr Tian away?I love Mr Tian .Best wishes to him!
