Everyone knows that the most famous Khmer smile in Tongwang City is the Khmer smile, in fact, when we are about to enter Tongwang City, you can see these Khmer smiles. The smile above the victory gate is particularly calm and very quiet. From the front and back, everyone can see the smile. The small door seems to pass only through a car. But standing here, closing my eyes, I can feel the scene when the army here triumphed back and walked through the door thousands of years ago, when the entire Angkor dynasty was strong.
