What is the Zen meaning of Japanese dry landscape architecture?

In Muromachi era, under the influence of Zen, dry landscape gardens appeared in Japan. Chen Zhihua said that most dry landscape masters are Zen monks. They not only brought the indifferent and secular mood into the garden, but also said that they expressed the eternity of getting rid of everything with the dry landscape. Without trees and flowers, there would be no glory of the four seasons and the growth of years. Without real running water, there would be no dryness and movement. Dry mountains and rivers symbolize stone mountains, white sand water surfaces and pools, and only simple shrubs adorn them. The most famous are Daejeon Temple and Long 'an Temple in Kyoto. Japan's dry mountains and rivers have a unique Zen meaning in Japan.
