My happy trip
Last summer, my father and I went to Rizhao city. We saw the sea, beach, ship and so on.
When we arrived there, I went to the seaside at first. The sea was beautiful; the coastline was very long; the sand was soft and smooth. The sea wave ran to the beach quickly. The landscape was very beautiful. I was very happy, I went into the sea and played with my father, but I drank some water. “Oh, the water is salty.” I said.
I played with waves happily. I sang, jumped and danced in the sea. Three hours later, I came to the beach and picked up some smooth and beautiful cobbles. I liked them very much. I found some shells too. They were beautiful. Two days later, we went back home. I was very happy because I went to the seaside!
