　My summer travel started terribly. I was at the Shanghai Railway Station buy a ticket to Hangzhou. I was going to visit a friend here and after that I would go to Xiamen for long holiday. I bought my ticket but turned around to pick up my bag from the floor and then I realized that someone had stolen it. Luckily I had all my money on my pocket, but the only clothes I had was those I had on. It felt very strange to travel without any luggages.
