According to the Pear Samray people of Kranhung, the Kulen hill region's Samray survived because of emigration in the days of the Angkor kingdom. After the 1967 revolt of Samlaut, Pear of Stung Kranhung area moved to Ta Sanh.
While some Sa'och live in Cambodia's coastal area, the Sa’och of the Kampong Som area fled from the Khmer kingdom and went to Trat Province, Thailand. The Sa’och are a mystery as they are racially different (Negroid) from other Pear groups but speak the same dialect. Because of their negroid features, Sa'och were sometimes called ‘people with tails’ in the Khmer language. Martin speculates the Sa’och inhabited the higher areas and the Samré the lower slopes and flatter areas before the arrival of Khmer from Champassak in about the 6th century.
The Pear cultivate upland rice by the swidden method.
They follow traditional religions.
