In fact, I have always paid special attention to safety and I am very fortunate. For example, today I have encountered 18 students, Dahan all the way, all the way guides all the way, I want to go to Dhaka University to visit, I was "caught" by a group of enthusiastic college students. How can you visit alone? Its too dangerous, and no one introduces you. Then I introduce myself to my name. Hey, hello, where do I remember, I am blind, and then I started. I went to the dormitory, the library, the playground, etc., and I still refused to let me pay the money. The little buddies were so enthusiastic that they led me to the stage and I was so flattered that I finally sent me to the sudden car. I am really grateful. Good people are safe for life!
