On a clear autumn night, Xiaohua got lost in the wild. How many ways can you help him go home?

First, when you walk in the wild, if you get lost, if you take a compass, it can help you distinguish between the north and the south and get out of the wild. Second, at night, Polaris will appear in the sky. Polaris always faces north, which can also help us distinguish between north and south and go out of the wild. The sun rises in the east and sets in the west. As long as we observe it, it can help us identify the east-west direction and get out of the wild. 4. Find a tree and observe it. It has lush foliage in the south and sparse foliage in the north. Or you can observe the stump, and the width of the annual ring is south; You can also observe the ants' caves, because most of them face south. 6. Where there are many rocks, you can also find an eye-catching rock for observation. The mossy side of the rock is the north side, and the dry and bare side is the south side. 7. If you have a watch, you can use it to tell the direction: divide the time you are in by 2, and then aim the quotient at the sun. The direction indicated by 12 on the dial is north. If you see an abandoned house, you can observe that its door faces south. You can also follow the direction of the current, because the water flows downwards and can take us out of the mountains. ……
