Yuanmou people's living conditions: surrounded by mountains, pleasant climate and lush trees. The trees on the mountain are evergreen all the year round, and the foothills are overgrown with weeds. Yuanmou people lived in such an environment. They chase small animals with sticks and stone tools, or go fishing in rivers and lakes with their bare hands, or pick them on the grass. Yuanmou's life is extremely difficult. They are often attacked by wild animals, by bad weather and by diseases. They can only rely on the strength of the group and fight against nature with simple tools.
