My summer vacation is coming to the end .I have spent a happy summer vacation with my parent and my younger sister. During the holiday ,we went to Dalian for a visit , I saw the beautiful sea over there, it was really amazing .I don't know how to describe this beautiful city . The sea water was as bule as the sky , and it was very clean as well . Also ,the beach in Dalian was very nice , we built a small sand palace . When I was swimming in the sea, as if I was a little fish , I like that feeling very much . That;s my trip to Dalian ,it's really unforgettable .
