This trip to Cambodia is the best place to go. I bought a Chinese guidebook, walked one by one according to the instruction icon, and listened to the historical stories of each room. In contrast to the black and white photos of young people, many of the original leaders ended up in prison. Khmer Rouge's tyranny, deeply feel our happiness in the peaceful era, hope that no harm will be done... Upload a few pictures, but you still have to experience them by yourself.
