The eight characters like their own soil and don't like it. So which direction to go and how to divide the soil? And colors, jewelry, etc. How to distinguish it from bentonite?

In orientation, the soil is not the center. You can know the location of your own soil by looking at the map of twenty-four mountains. The color of soil is yellow and brown, and bentonite can't be distinguished from bentonite. Jewelry has nothing to do with bentonite. However, if you are sure that you are short of soil and want to make your own soil rich, you can find your own soil in some identifiable places, but in fact, people who are short of soil can use bentonite and replenish water at the same time. You are likely to be biased against the theoretical explanation.
