The Chu Ru language belongs to the Malayo-Polynesian group. They adopted a sedentary life and practised farming very early. Nowadays they also practise sericulture and life is fairly stable. Apart from cultivation, they raise cattle, pigs, goats and poultry. They make bamboo and rattan handicrafts and tools such as sickles, picks and knives.
Some villages are well known for their pottery.
Hunting and gathering and picking are sideline occupations in every family. After them comes the shaman who plays an important role in spiritual life. Usually, the extended family of the Chu Ru comprises 3-4 matrilineal generations living in an elongated house. Monogamy is observed. The young woman chooses her own husband.
