The year before last, I went to Chongqing with my family.
First, we took a bus to Zhengzhou. Then we went to Chongqing by plane. It was my first time to travel by plane. I was very happy and excited when I got on the plane. Before the plane took off, all the passengers (乘客) had to turn off their mobile phones. At first, I was a little nervous. I saw the blue sky and the white clouds through the window. The clouds looked like piles of cotton.
