A visit to xi'an

I went to xi'an because of the request of work ..It is an old city,and everything there is amiable.I love the people there ,and also the old city.ancitent citywall,and the relics of the city.when I walked in the street I imagined thousands of years ago ,there was the centre of the Central Plains Area .there was ever prosperous,but now it is a new appearance .Time can change everything ,no one is special.
