Dear Jack,

I’m glad to hear that you are going back home during the summer holiday and you want to bring some gifts for your mother that symbolize the Chinese culture.

As for my advice, I think cheongsam [tsæm] 旗袍, a very beautiful traditional dress, is a good choice. With the fine silk and the delicate design, you mother will definitely look elegant [elnt]高雅的，优雅的in it. What’s more , the Chinese knot is also highly recommended.

The knot is popular as it stands for good luck. Such a pretty and meaningful gift will surely impress your mother and family.

Have a good vacation and please send my best wishes to your mother.

Yours，

假定你是李华，自制了一些中国结。给开网店的美国朋友Tom写封信，请他代卖，要包括：

　1.外观（尺寸.颜色.材料）2.象征意义3.价格

Dear Tom,

　How are you doing? I wonder if you could sell some Chinese knots for me.

　I made them myself with red silk threads, cloth and other materials. They look really beautiful in the shape of a diamond, about 5 inches long and 4 inches wide. In China, these knots stand for friendship, love and good luck. People can either give them as gifts to friends or hang them in their houses.

　They are only 12.99US each. If anyone wants to know more about the knots, let them write to me. Also, do let me know if you need further information. Thank you!

　　                                                            Yours,

Li Hua
