At the northernmost end of the Arctic Village of Mohe, the locals built a north-character square. First, it shows that this is the northernmost end of China. Second, point out the direction, this is the north. Third, the moral, find the direction, find the goal of life. Will not be blind. We often say that when we find the north, we know the east and the south. Because there is a Big Dipper in the sky, the north is easy to find. If we know the north, don't we know the other directions?
