[h-] Harry Potter is in [1] front of the [-ong] temple where in the middle of winter. He is nearly freezing to death in the rock garden that is covered with snow, so he gets some 共 seaweed out and lights it on 火 fire with his wand. This way he can slowly 烘 warm by fire his cold body there in the rock garden. He can't go inside the temple because the monks have a thing against wizards.
