Welcome to Black Bear Ridge, a place with beautiful mountains and clear waters and hordes of wild animals. Before entering the forest, please be sure to keep this survival rule in mind. After sunset, do not respond to any voice calling your name; do not accept the honey delivered by Brown Er; if the sound of a chainsaw exceeds ten minutes, please hide in the nearest tree hole immediately; never count the number of bears in the forest. I thought it was just a prank played by tourists, until I saw with my own eyes that those who violated the rules disappeared into the foggy woods.
