How can we make Shanghai more beautiful?

Shangshai is my hometown,and there will hold the EXPO after two years later,so we need to make our city beautiful which can help us showing our great country,and city。In my opinion,there are two important points that we need to achieve。Firstly,if we want to our hometown became a beauty city,we would overcome many bad habits;secondly,the most important thing,we are going to help each other when they need our help,or a smile,because more beautiful souls can make Shanghai more beautiful,and more。
