A arrived in Beidaihe at about 2 o'clock,and immediately took a No.5 bus to the sea area.The beautiful blue sea was so large that I couldn't see the other side of it.After getting off the bus,I went straight to the shore.Taking off my shoes,I put my feet into the water.The water was cool,and walking in the water was such a great joy that I didn't want to stop.Then I collected shells.When it got dark,I sat on the shore,watching the sea.The night scene was simply marvelous!

　　Finally I had to go back.It was an unforgettable day in my life.
