After telling me 88, I said goodbye to Zhangjiagang. To tell the truth, there is only one place in Beijing that is the most interesting, and that is the Beijing Science and Technology Museum. Just arrived at the gate of the Science and Technology Museum, a cold wind blew at me. On closer inspection, it turned out to be a balloon that fluctuated up and down. It looks very proud. I waited in line for a while and finally got in. Gu Yuqi and I came to the first floor excitedly. We touched here for a while, looked there for a while, and were curious about everything. Gu Yuqi and I both like the "water pedal". All you have to do is sit on it and keep stepping on it We sat in the chair excitedly, but I was in pain. I always fell down. We were listening to others chatting while stepping on it, and suddenly we heard a man say that there was no second floor, third floor and fourth floor. We looked at each other and almost vomited blood, but it was only half an hour before the assembly time, so we rushed into the elevator, because the elevator here was at the front door and out at the back door. As soon as we got to the second floor, we wanted to squeeze out. It was so comfortable. Wandering around the west, I found nothing interesting. At this time, Gu Yuqi took me to a place that seemed to be a farm. I want the farmer at the top of the screen to water and fertilize the plants, but the machine seems to be broken and keeps doing the same thing, so we are disappointed to see something else. Gu Yuqi and I can't find anything interesting. Suddenly, Gu Yuqi asked me what time it was. I turned on my cell phone and found that there were still five minutes left. Gu Yuqi and I hurried to the meeting place and saw many people eating ice cream, so we asked Tang Yu where to buy ice cream. She thought about it and replied, "I bought it on the second floor." I nodded and regretted not going to the second floor. At this time, the tour guide informed us to go back to the dormitory, and we were reluctant to go.
