优质解答 Sunday Fine Tianjin is my home town.These years the city has changed a lot.It is getting more and more beautiful.Last Sunday I took my friend around Tianjin.We not only tasted delicious food but also visited the Haihe River.It was so fantastic that we really had a good time.However,during the tour some bad behavior was noticed by me.Some people didn't stop at the red lights when they crossed the road.Some people climbed over the rails.Some other people threw away rubbish everywhere.I felt ashamed.I think everyone should obey the traffic rules and keep our home town clean and tidy.
