It all started with ancient mainland China.
The continents were all intact and people lived in tribes.
Hundreds of people co-existed.
Tribes could be formed if people lived through four seasons and developed their own survival system.
It was seldom that tribes formed alliances since they usually had just about enough food for their own people.
Nevertheless, co-existence of tribes would lead to the formation of new tribes.
Since there was a language barrier among the tribes, those who preferred not to talk would signal.
Written words were almost identical, albeit limited to simple systems.
For example, drawing an 'O' on a particular region meant that it was safe, and an 'X' symbolized danger.
Red lines beside the crosses meant that corpses had been found. Circles within the circle meant that tribes were living in that area.
Of course, peaceful co-existence was usually just a facade.
