回复：just be strong and try not to lose temper in front of her,

Thanks. you are so considerate. I taught her some kid's songs, and we sang tiogether last night. She had a good sleep, and we visit a friend this afternoon. she is happy. I shold stop anxious. It is stupid for me to keep looking back. One of my friend, he quited assiatant professor position and got board, now he works in a top pharmacytical company with triple his former salary.I really appreciate your suggestion and support. I feel much better after I read all of the positive and warm response.
