What is the survival mechanism of the three people in Three-body?

First of all, three people must be different from one person. All three people are very small, and they all emit some tiny light, which is about the size of ants. So how did they survive?

First of all, they certainly don't live by eating bread and eating like human beings. They are higher-tech creatures, and they have their own set of survival criteria. Moreover, the brain of the threesome is very developed, much more developed than ours, and its memory is very strong. The brain will store a lot of information, and then when they encounter some problems, they will extract relevant information from the brain to solve the problems. And the trio will fit together, and when they fit together, they will be divided into many cubs.

So they are divided into many individuals, and each individual carries a part of memory, which is also the reason why the three-body is still learning, because basically it doesn't take any time, and it takes very little time. The way of communication between three people is to send and receive through computer radio waves, which is a bit like telepathy we humans say. Moreover, the development of Santi people is not optimistic. After a long development, they finally have a generation of civilization and a certain social stability, but they met us.

They decided to transfer their targets and immigrate to the solar system, because the existence of earthlings gave them a great deterrent. Later, because humans developed spaceships, they had to choose to escape. They have suffered more than human beings. They have no food and clothing, and there is no relationship between men and women. Some drift again and again, destroy again and again, and be born again and again. And the survival of the trio is very cruel. They have no Garden of Eden, they have suffered too much, they can't have love, they can't have autocracy and they can't have centralization.
