There are 3 major nations living in Cambodia for many years. They are Cambodian chinese, Cambodian Muslim and typical Cambodian people and those people make a living from different jobs

– Cambodian chinese ( they are traders, selling things and businesses… )

– Cambodian Muslim ( they are fishermen and they mostly live along the river & lake to make it easy for them to do their job )

– typical Cambodian people ( they are mostly farmer growing different crops, rices, corns, potatoes…etc ).

But recently since 1979 after Cambodia finished their civil war there are one more nation is Vietnamese people living in Cambodia.
