     Last weekend, I helped my grandparents  their trip to  Dalian. On Saturday morning,  together with my

grandparents,I search the Internet for the train schedule,the weather in Dalian, and some hotel informations.

In the afternoon, we went to the train station and managed to buy two tickets for my grandparents although

there had a long queue. After the dinner, I packed into the suitcase the things what my grandparents would

 need, such as clothes, glasses, an umbrella, and a map. The next morning, I went to the station to show

them off. Waved goodbye to them on the platform, I felt happily for them and wished them a safe journey.
