Flexible and unpredictable, giving people a fresh feeling.
Such pictures can be called ethereal pictures.
Ethereality is an artistic conception.
Aesthetician Zong Baihua believes that emptiness refers to the "spiritual space" contained in the artistic conception.
This space is an organic aesthetic psychological field uniquely created by the artist’s imagination, with aura flowing through it. This is the poeticization of the Chinese people's cosmic consciousness and life sentiment. When expressed in the artistic conception, it is an ethereal beauty.
Voidness can be understood as a "spiritual space". It is three-dimensional and boundless, which is the "infinite realm" described by Zhuangzi. This space also has its depth, breadth and height, so works that can present a superb and clear cosmic consciousness and life sentiment in a magnificent and deep space in the artistic conception are both ethereal and most beautiful.
From Sui Dynasty painter Zhan Ziqian's "Spring Outing", Northern Song Dynasty painter Fan Kuan's "Streams and Mountains Travel", to Qing Dynasty painter Shi Tao's "Landscapes with Sound", every classic masterpiece embodies It represents the communication and collision between the creator’s heart and nature. The artistic tension of the work transcends time and space. What the painter shows is a broad mind, a pure soul, and endless reverie, leaving the viewer with a fresh and ethereal world.
