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 .
