What are the two kinds of tattoos of primitive people?

There are roughly two kinds of tattoos of primitive people: one is painted on the body with pigment, and the other is carved with sharp tools. Tattooing is a fashion that primitive residents generally pursue to show the beauty of human body. For example, aborigines in Australia, people of the same race tattoo the same pictures and words on their bodies to distinguish them from other races. Mosayan people living in the Pacific Islands must get tattoos when they reach the age of 16 to symbolize adulthood. Eskimos in cold regions, when men reach the age of 8, begin to prick their faces, chests, arms and thighs. Tattooing is more common among American Indians. In the south of China, there is also the custom of "depicting his body with patterns and absorbing it". This tattoo custom is quite common among many ethnic minorities in China. Tattoos reflect the aesthetic taste of primitive people.
