After five years away in my hometown, I find that                
the neighborhood which I used to living in has changed           
A lot. The Sichuan Restaurant and the older fish shop            
across the street from our middle school were gone.               
There exist now a park that has a small river running            
through. The factory at the corner of Friendship Street or      
Zhongshan Road has been moved out of the city, and sports        
center has been built in their place. The market at the corner of
friendship Street and Xinhua Road has been given way to         
a supermarket. Besides the bookstore next to our middle          
school is still there.
