Suppose one of your friends is going on a self-tour in your hometown. Write a letter in about 100 words to make a suggestion to him/her. Do not sign your own name at the end of your letter, using Li Ming instead.
Dear Mary, Glad to hear from you. You have made a right decision to travel in my hometown, Sichuan because it is a place with picturesque scenery.
Self-tour is always my favorite, too, as it gives me more freedom to choose the beauty spots and arrange the tour. To you, a camping?lover, I highly recommend the Ice Mountain in Songpan County. First, you can directly go there by bus from Chengdu or Mianyang. The accommodation in Songpan is very convenient since there are quite a lot of private hotels with clean rooms at low price. Then you can hire a guide who will prepare a horse, a tent and some other things for you. After that, you will visit the beautiful scenery on horseback by following the guide during the day and enjoy camping at night. My journey there last July has really brought me great pleasure and unforgettable memory.
Wish you a happy tour.
