Everyone has his own understanding of life. No matter the understanding is mature or childish, people do not like to be preached or nagged. If the words are not pleasing to others’ ears, they can easily be accused of absurd nonsense. Therefore, "speaking out" is the last thing I want to do. From ancient times to present, there are numerous examples of people receiving misfortunes because of talks. I understand this well as a man of middle age.

What is maturity? Maturity is knowing when to keep quiet. However, some things are destined, and both my life and yours have reached this point. It all began when I woke up in a morning.  

1. The Beginning

In 1973, I was born in a rural area. At that time, most people in the countryside gave birth at home, and midwives from the village delivered the babies. Nowadays, urban children rarely have this experience. When I was in elementary school, I saw the midwife who delivered me, and I found it interesting that "this old woman delivered me!"

Regarding my birth and the time after, there's nothing extraordinary in my recollection. If I have to mention anything unusual, there are two points. First, my mother did not have breast milk when I was born, so I relied on rice soup and a little milk powder to survive. Before I was a month old, I was affected tracheitis, and the only available treatment at the health clinic was painkillers and oxytetracycline. The medical conditions were scarce. So, under my grandmother's direction, I was treated with cabbage and pear soup, which was poured down my throat. Then I was wrapped in a quilt to sweat. Second, my fontanel didn't close in time, which worried my mother: "What shall we do with this unlucky child?" My parents decided to give me calcium supplements, small calcium carbonate tablets with a sweet taste. I ignorantly regarded those tablets as candies and would eat them stealthily and I ate these "little sweet pills" blindly for several years.

During elementary school, social background was important. My family was considered to have eight generations of impoverished farmers, which made me very confident when filling in all sorts of forms. In primary school, I was boringly ordinary as all rural children. However, when everyone strived to be a member of the Little Red Guard, I was quite resistant. As my study performance was very good, I was also bestowed a red scarf. As a young child, for unknown reason, I had a strong fear of joining an organization. After primary school, I did not join any other organization.

Yi refers to the information from high frequency civilization that this book transmits.

Yiology is a means of practice of the information of Yi on the Earth.

Yi is not to make you believe, but to teach you how to question! 

As a child, I loved to lie in the yard at summer nights gazing at the shining stars. The summer night sky was very beautiful. The children loved to argue whether there were more stars in the sky or more people on the earth. At that time, I had not attended elementary school yet, but I already knew that not only were there stars in the sky, but there were also stars beneath the earth's surface. I also knew that we were suspended in the middle. I always felt that there was a familiar place deep in the starry sky. Later, as air pollution worsened, that familiar feeling gradually faded. I'm just telling the truth, not claiming to be extraordinary. Every child may have various fantasies.
