<h3> Today, sadly we will leave Philadelphia, leave America, leave the place where we studied lots of things and had fun a lot. Our plane will take off in 1:40am at 7/29.</h3> <h3> Today morning, we went to Old City Philadelphia, Liberty Bell and Independence Hall. I felt the freedom of Americans was not easy.</h3> <h3> The first post office in America, it is still using now!</h3> <h3> The first church in America. Lots of famous people like president came for prayer.</h3> <h3> We had "Cheese Steak" for our lunch. It is dilicious and very famous.</h3> <h3> Goodby, Philadelphia! Goodby, Newyork! Goodby, America!</h3>
