Professor He's Digital Human construction was extremely complex. First, he established a complete set of digital physiological cells, simulating the functions of cells, then used these digital cells to construct digital tissues, which in turn were used to create digital organs. From these organs, he built systems, and finally, from these systems, he assembled an entire human body.
The highest stage of a Digital Human is the 4.0 "Digital Intelligent Human," which not only possesses a virtual human form, anatomical structure, and physiological biochemical functions, but also possesses independent consciousness and human intelligence. It is a complete virtual person, a person living in the digital world, much like the people in the movie "Transdimensional Hacker."
