About two year ago, it is my first time to left university and return home. I bought a train ticket. When I arrived at the train station and waited for train. suddenly, I realized that I could not find my ID card. In China, if you do not bring ID card, the staff do not allow you to take the train. I did not go with my friend so I had no one who could give me some suggestions. Fortunately, a policeman on duty at the train station found me looks anxious and asked me what happened. I told him the problem. Then he advised me to call my roommates to make sure if I leave my ID card in dormitory. My roommates said yes. However, the train would leave after 30 minutes. The condition seemed to be more serious because 30 minutes is too late to allow my roommates bring me ID card. The policeman suggested me that he could help me apply for a temporary ID card so that I could use today. Thanks for his advice, I successfully taken the train in the end.
