Dear Mary:

　　I am so glad to receive your letter and know that you going to pay a visit in China,specially in Yunnan Province.As a native,I'd like to tell you that the best time for visiting Yunnan Province should be in April or May,and the best place to visit is Xishuangbanna.Because of the fine weather,you may travel by long-journey bus.And you can experience the native life and taste the local delicious food.I think it will offer you a quite different taste of traveling.Everything is so unique there,the people,the custom,the animal ,the plant and the climate there in Yuannan Province.

　　Hope this letter helpful to your journey in China.
