After a person dies, if he can enter Godsociety, his soul will enter Godsociety, and his body will be dispersed into smoke and dust and disappear; if he cannot enter Godsociety, his soul will be dispersed into smoke and dust like his body and disappear.
The soul of a person who enters Godsociety is sent to the baby-making machine, which transforms the soul into a Godbaby. In the process of transforming into a Godbaby, the soul is added with forgetting agent, and after becoming a Godbaby, it loses its memory of Human Society.
People are created by people, while Gods are created by machines. This is why people often act emotionally and mess up the law with emotion, while Gods are not moved by emotion and do things objectively and fairly.
Mao Zedong's situation is different. He was sent by Godsociety to conduct investigation and research in Human Society. Godsociety preserved his god body. When his time of being sent expired and he returned to Godsociety, he did not go through baby-making machine, but directly returned his soul to his original god body and was reborn in Godsociety. Therefore, Mao Zedong was not affected by forgetting agent and still remembered his past in Human Society.
Due to work needs, Gods and Godhumen can recall their past in Human Society to a limited extent according to law.
Since Godsociety once preserved Mao Zedong's god body, after Chairman Mao's death, Human Society followed the example of Godsociety and preserved his body forever, hoping that Chairman Mao could return to Human Society one day and lead the people to build a more beautiful Human Society.
Only Humen can transform into Gods and Godhumen, while other animals and plants do not have this function. All Gods and Godhumen have a past in Human Society and have natural feelings for Human Society. This is why Gods take special care of Human Society. We "have Gods three feet above our heads." (颜宾)
