Bayon Temple: Exploring the Smile of Khmer “Smile of Khmer” refers to a smiling Buddha head statue, which is located in the Bayon Temple. This is one of the 3 great temples in Angkor. The smile of the Buddha’s head is serene and mysterious, as if hiding the secrets that the world cannot understand. It is unique cultural attractions in the Angkor ruins. It is best to avoid the noon time when shooting photos at the Bayon Temple. The mottled boulder under the direct sunlight seems to offer no sense of perspective. In the evening, when tourists are few and the light is soft, you can often see the monks leaving one after another, which is more suitable for taking pictures.
