Saturday,

July 7th

Dear Lily,

How are you? Long time no see. I wish everything goes well. Yesterday we went to Qinhuangdao. It's a

beautiful city. We went to Shanhaiguan. Then we went to the seaside. The sea is wonderful. But my brother

hurt his toe when he walked on the sand. We took some pictures.

Today, we will go to Beijing. It is great. I want to stay there for five days. We will visit Tian'anmen Square,

the Palace Museum and the Great Wall. I want to buy some gifts for my friends. Where did you go last week?

Please write to me soon.

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　Yours truly,

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　Kate
