Near the Old Market in Siem Reap, Cambodia, there is a temple called Wat Preah Prom Rath. Maybe it has been renovated in recent years. When you see the splendid appearance of the Wat Preah Prom Rath temple, you may not expect it. This is one of the oldest temples in Siem Reap, built in the late 15th and early 16th centuries. It has been more than 500 years old. When I first entered the door, I entered the temple of the Thai Grand Palace with a trepidation. I was afraid that I would pay for the tickets, and I was afraid that I would wear trousers to enter the temple. However, the temple in the afternoon is much quieter than I thought. There are almost no visitors. Occasionally I saw one or two locals taking a nap under the big tree. Cambodia's Buddhism combines the Buddhist religious system with the secular political system. It is this theocracy that combines royal power and religion. It has laid a good political and social foundation for the prosperity of Buddhism in Southeast Asia. . Wat Preah Prom Rath Temple, like other Buddhist temple buildings in Southeast Asia, draws on the Buddhist architectural art of India and Sri Lanka, and combines local characteristics to develop a Buddhist architecture art with a Southeast Asian style.
