Mr. cheng and his friends are having dinner at a local restaurant, and Mr. Beier asks if he likes the food. He says that he does, and that the food smells good. He tells the group that they should eat with them the next time they are in town. The director has announced that they will have to hike 5 km to the village entrance, so they can all eat together. The group decides to follow the directions given to them by the director. They will go west along a lake, then change back to the north, and then they will return to the starting point.
