To teach is usually to contact the school. The school will solve your accommodation problem and won't let you sleep in the ground. Accommodation is generally at school, so is eating, of course, excluding some poor schools with limited conditions. Specific things should be discussed in detail with the contact person, and some may go to a fellow villager's house to eat and live.

Accommodation is closely related to the local weather and environment. Different places have different weather and environment, and you need to know the specific things yourself.
