Factions!

Beyond the Camp where Xiaohe lives, another group of people are gathered together and they all have black animal hoods.

Based on their means of dressing, they are indeed a group of women, and the most interesting thing is that they seemed to live near a huge water body, their houses were created on top of trees though. 

The leading woman had the hood on her head lowered and thus easier to see her entire face. She had an attractive face with an appearance of a 21-year-old woman. Her hair was also tied up with small beads hanging from it. 

The group seemed to have created their tribe but from the appearance of the location they were gathered and houses hanging on tall trees, they had not formed their little tribe lately.
