I'm applying for one week's leave of absence from the 11th to the 17th, in order to return home to see my father, who is now dangerously ill.
I should be very much obliged if you grant me my application.

Dear Chen Hua：
How are you these days? I’m writing to you because I need your help. I’m thinking of coming to Shanghai. I will stay for a week. During the time, I hope I will be able to visit Suzhou .I’ ve got a picture of the Tiger Hill(虎丘), a beautiful garden in Suzhou . The scenery is strongly impressed on my memory. In the last letter you told me that you had been to Suzhou twice. Would you like to tell me something about it?
Expecting to hear from you as soon as possible.

Dear Li Ping,
Glad to have got your letter. It makes me happy that you are coming to stay in Shanghai for a week . I think we can meet each other and have a good time then.
Now let me tell you something about Suzhou . Suzhou is famous for its beautiful gardens. There are more than 100 in all, they say. Among them the Tiger Hill was my favourite. Thousands of years ago, a king was said to be buried there with his treasure. Unfortunately, I didn't find the treasure, but we did have a good time there. I've taken some pictures there . If they some out well, I'll send you some.
Suzhou is worth visiting. I hope you'll pay a visit to it. I'm looking forward to your arrival.
