This place is not a tourist attraction, so it can't be evaluated by its scenery, interesting and cost-effective. It is a history of Cambodia. In 1975, the Khmer Rouge led by Polbert seized power. In the following three years, about 3 million Cambodians died of abnormal deaths. Once a concentration camp, nearly 10,000 remains were excavated. Today, thousands of victims'skulls are stored in tall Buddhist pagodas by age, sex and barefooted into the pagodas. The skeletons look at you as if they are telling you about a terrible past and suffering on Cambodian soil, one of the most bloody and violent man-made catastrophes of the 20th century. When we get to Phnom Penh, Cambodia, we can go and have a look.
