Thanks to Laomao's reply. I think I can understand what he has been feeling since it happened. He has been doing everything carefully and obeying all the rules strictly, such as recycling garbage. We talk how to behave even in the trivial thing in the life. He is an responsible man. Hope he can get the study permit extension and finish his thesis and have a good future. Who has the similar experience or heard of the similar case? Thanks for your great help!
