<human>:  I have a question about the Killing Fields of Choeung Ek. What is the meaning of the name Choeung Ek?
<bot>: Choeung Ek is a Khmer word meaning “field of bones”. The Killing Fields of Choeung Ek are a place where the Khmer Rouge killed thousands of people. The Khmer Rouge were a communist party that ruled Cambodia from 1975 to 1979. The Khmer Rouge were responsible for the deaths of over 2 million people.
