The Queen's Palace is one of the most beautiful ancient sites in Cambodia and one of the most worthwhile scenic spots to visit. The Queen's Palace is actually a monastery. Its sense of space is astonishing, which is when the Emperor gave a monk the equivalent of a hermit temple. From the aerial view of the Angkor complex, we can see that compared with the overall area, including the length of the approach, the building itself gives a feeling of a word - "empty". The "empty" is a part that human beings can not reach yet. It surrounds the temple entity with a large "empty" and quotes Lao Tzu's philosophy that "existence and non-existence are interrelated". The existence and non-existence, the empty and the real are actually two entireties. While modern architecture is being built, it is hoped that more and more entities will come into being, and so will our family. The "empty" is gradually forgotten, and the "empty" part is to help you find the existence of "you". When you get to the center, there will be a phenomenon of doors on all sides. Looking closely, you can see the Naga snake stirring the Milky sea. If you pass through every door, that door will tell you that the universe is still stirring, life is endless, and every door is a hint of religion.
