How do I prepare before going to the homestay?

First off, you should go for a few walks before going trekking as it will help you get your legs back. 

For the homestay, there is not much preparation. Making sure that you have packed everything you need to make your stay more confortamble is most important. Bring a small bag with the clothes change of clothes. You should bring something warm, as the nights will cool off, sometimes dropping as mush as ten degrees. Other things you might want to bring with you are a mirror, toilet paper, your favorite tea or snack, flashlight, and a book.

Further preparations to make your stay even more special would include learning a short song to sing after dinner. It is a cultural tradition to sing after dinner, and if you start off by saying you would like to sing a song, then all the better. You can bring gifts for the homestay owner, things like pens, pencils, and books. Other great things to bring with you to the homestay, and all over asia, are pictures of your home, you and your family. The pictures always become a great conversation piece.
