Hi all, Thanks for your concerning about my lost schoolbag! The good news is that someone has returned the envelope with all the documents inside to the doorway of my apartment this noon. I just got to know about this when I got home. Though the laptop is still missing, I am happy enough for this fact. Here I will say thank you to all the people who have paid attention to my case and tried to help me. I do appreciate your kind effort. Thanks you so much! Wangyang Tu
