The people were born in the early 1800s and the story about the eyes is already there. Those eyes are not of the genie type and only certain people are shown to see those eyes. The story of the eye is believed because it is not just one or two but many people who saw it. It can be seen for a period of two to three years until after that they are no longer visible and disappeared.

The forest area is seen first before it was divided. The land is divided into fields as much as two to three acres for one family after seeing in advance the condition of the land that will be explored for paddy and gardening. They move around because they want a comfortable place and also want (good) fertile land to grow rice and garden. The rice is stored in a place called 'durung'.
