What are the basic characteristics of Da Yin Xi Sheng and Elephant Silence?

“The loud sound is loud, but the elephant is invisible” is a famous saying in Laozi, which represents a characteristic of classical aesthetics. The "big sound" and "elephant" mentioned here do not refer to specific sounds and images, but emphasize the natural and absolute artistic realm. Specifically, "Great Sound and Sound" means that the most beautiful music does not exist in the form of specific sounds, but in those silent, non-material, and transcendent realms, that is, the artistic conception of music. Similarly, "elephant is invisible" means that the most beautiful images do not exist in specific material forms, but intangible, non-material, artistic conceptions that transcend reality, that is, the realm of art. In other words, "The big sound is loud, the elephant is invisible" expresses a kind of artistic beauty that transcends the material world, emphasizing the inspiration, artistic conception, charm and other non-material factors in artistic creation. This idea has had a profound impact on Chinese literature and art and has become an important aesthetic standard in traditional aesthetics.
