What are the manifestations of aesthetic thoughts in ancient gardens in China?

As a comprehensive art, garden not only includes architecture, flowers and trees, water control and stone folding, but also includes painting, calligraphy, sculpture and poetry, which embodies the idea of "harmony between man and nature [1]" in China's aesthetics. Influenced by this idea, Ji Cheng, a gardener in the Ming Dynasty, proposed in the first article of Gardening Governance that the highest realm of ancient gardens in China was "self-opening, although it was artificial".
