Last weekend, I helped my grandparents prepare for our trip to Xi'an. On Saturday morning, together with them, I searched the Internet for the train schedule, the weather in Xi'an, or some hotel informations. In the afternoon, I went to the train station and manage to buy two tickets for them since there was a long queue. After dinner, I packed all the things that might be need into suitcase. And the next morning, I went to the station to see them away off. Wave goodbye to them on the platform, I felt very happy for them and wished them a safer journey.
