<div>This National Day I went to Ningbo, my second hometown, where I used to live with my parents for 6 years and finished my primary school study. I really got a happy and carefree childhood there. As time goes by, those memories become more profound instead of being forgotten. They still often appear in my dream, saying how I miss those past time.&nbsp;</div><div>I haven't been there for such a long time that many things have changed or disappeard when I went to see them. My primary school has been built into a chemical factory, I couldn't find even one familiar thing at all. The playground which we used to run or play or do a morning exercise on have become a place where many chemical products were put. Our classroom buildings have become the living quarters of the stuff of that factory. And those food stands which would be opened in front of our school gate after school could not be found any more.&nbsp;</div><div>When I finished visiting and came back home, many thoughts crowd into my mind. I didn't know whether it's sadness, disappointment or just nostalgia, or maybe I got all of them. Nothing could last forever, which was the only reason I could tell myself.&nbsp;</div><div>Anyway, I am still very glad to have a chance to revisit my second hometown after a long separation.</div>
