I used to study on the Sinan Road in Shanghai, but for the first time I knew where Sinan was because a Sinan sister came from the department, so I went home to play with her. The whole county town is crossed by Wujiang River, which has a special flavor. Sinan Middle School graduated from my sister is the only one in Guizhou Province built in the county, which shows that this county still attaches great importance to education. My sister's father introduced that Sinan has the title of the Prefecture in central Guizhou, and its history is longer than Guiyang. The only thing I can't stand is that I have to climb mountains when I walk around the city. Five of us in Shanghai are very weak.
