How did the ancient gardens in China come into being?

The ancient gardens in China were developed under the dual purpose of the ruling class's living and sightseeing. The main characteristics of this kind of garden are to adjust measures to local conditions, dig up land to build mountains, arrange houses, flowers and trees, and use the environment to organize the borrowing of scenery to form a natural and interesting garden. The so-called natural humor is to create all kinds of ideal artistic conception in the garden by summarizing and refining the natural landscape materials in the design. It is not a simple imitation of nature, but a reproduction of nature. "Although it is made by people, it is natural." Therefore, we must have a deep heart and be proficient in painting theory in order to achieve the ideal artistic effect of gardening. Under the influence of this traditional habit, after long-term practice, a natural landscape garden with high artistic level and unique style has gradually formed in China.
