It is several months ago when I have to go to Beijing for training my teaching skills. Because I didn’t buy the fly tickets, I had to go there by train. It was the first long journey for me. Listening to my MP3 player, I just reached the station while enjoying the music.

At the beginning of the journey, I felt so excited. That was the first time for such a long journey and to go to the capital of our country by myself. I paid much attention to the scenery when the train passed away fast. After half a day’ appreciation of the scenery, I found many people were listening to their MP3 or MP4 players. That reminded of me. I began to take out my mini MP3 player and listen to the music I prepared for this journey, thinking about what would happen when I arrived at Beijing. There must be a lot of future friends here who went there for the same aim with me…

I felt quite boring at night when there was no scenery at all except for the darkness, especially after turning off the mobile TV. Most people began to sleep, the around was in silence except for the scream of the train, but I didn’t want to sleep at all. I flipped the music menu in my mini MP3 player again and again and chose the music I wanted to listen to, finally falling asleep. When I open my eyes, it was already a sunny day, the destination was closer and closer. My passion and excitement started animated again.
