The first stop we went to was the killing field (The Killing Fields), also known as the clock house. In 1975, the Khmer Rouge conquered Phnom Penh and seized power. In the three years since, about 17,000 people were executed here, and more than 9,000 bodies were exhumed from the killing field, and most of them were unarmed people. In 1988, the government built a pagoda here to commemorate the death of the soul, the pagoda is 15 stories high, made of resin glass, according to age and gender, densely placed more than 5,000 skulls excavated from the tomb. Although the plants used to kill people read the introduction before entering the bell house, some psychological preparation, but when I stood in this small space, facing the tired white bones in front of me, I imagined the scene of the tragic people at that time, I was still shocked. Everyone who entered here was silent, and everything around him seemed to be still, as if afraid of disturbing the wronged souls. From the killing field, sitting in the tutu car, watching the blue sky and white clouds, breathing the smell of sunshine, gradually slowly from the sad atmosphere.
