People lived well in the north, and the ancients preferred the south because it was not so cold in winter. Today, some people think that it is better to look at the north from the world, but it is better to look at the north from China, better to look at the north in southern Jiangsu and better to look at the north in Shanghai. This phenomenon has something to do with the earth's magnetic field and the universe.
The electromagnetic field generated by the earth's rotation is different in the north and south, with more soil in the north and more water in the south. The material in the north is thicker, the northerners are stronger, and people's feelings are stronger.
Some people think that the universe has no ups and downs. The so-called ups and downs are divided by people. Some people have ups and downs, and no one has ups and downs. Yes, people are good at their own interests, attach importance to exploration and pay attention to their own gains and losses.
Because there are human beings in the universe, people will divide the universe up and down according to its characteristics. There are no points at present, and they will be divided later.
