One possible version :
I would highly recommend Beihai Park . Beihai Park is situated in the middle of the city of Beijing and it used to be a royal garden , Inside the park , there is a large area of water in the middle of which stands a green island with a white pagoda on top . The park gives different looks during the four seasons : bursting flowers in spring , white boats in summer , colorful leaves in autumn and shining ice in winter . For hundreds of years , the park has welcomed its guests with sweet smiles and presented them with a vivid picture of our ancient civilization
