1. Guanyin clay is also called kaolin clay, also known as bentonite, bentonite, sweet clay, bentonite, clay, and white clay. Guanyin soil is rich in silicon, zinc, magnesium, aluminum and other minerals. It is a clay mineral with quite stable chemical composition and is known as the "universal stone".

2. Guanyin soil was generally used by hungry people as food to satisfy their hunger during periods of famine, and eating it temporarily relieved hunger. But it cannot be digested and absorbed by the human body. After eating, the abdomen will be bloated and it will be difficult to defecate. Eating a small amount is not fatal. Although you will not starve, people will still die due to lack of nutrition.

3. During the great famine, as long as you can walk, you need to go out to look for food. If you find food, you can also make it by burning firewood. In 1942, villagers could travel sixty miles round trip to carry Guanyin soil. Poor people use the steaming method at home. The Guanyin soil is kneaded into a ball with wild vegetables, steamed, and swallowed like a nest.

4. There is now an antidiarrheal medicine called "montmorillonite powder", which uses the astringent effect of Guanyin soil in the intestines. Therefore, this soil is more filling than Wowo, and eating even a little bit will make people feel full in the abdomen. The soil stagnates in the intestines and stomach and cannot be pulled out at all. The final result is that the stomach is bulging like a small watermelon and is very hard when knocked (it turns into a stone). At this time, it is time to die.

5. Guanyin soil does not mean that you will fall to death or swell to death if you eat it. It is okay to eat a small amount. Many people survive by eating Guanyin soil. Eating steamed Guanyin with soil can indeed extend your life, but eating it for a long time will definitely lead to death from swelling. No one wants to eat this unless absolutely necessary.
