Many intellectuals were killed and books were burned during Khmer Rouge period (1975–1979). Literacy rate of Cambodia is 76.3, which is the 133rd place out of 183 countries. It is pointed that this low literacy rate is one of the factors that hinders development of this country. TZU DESIS Lab will make a free downloadable picture book written in Khmer language for Cambodian children in collaboration with Oya in Cambodian Mekong University in order to improve this situation.
