As a real environment, gardens must ensure that visitors feel convenient and comfortable in their life when visiting, and ensure that the environment is sanitary, pleasant, noiseless, luxuriant in plants, convenient in transportation and complete in living facilities, etc., which are suitable for people to have a quiet rest and show the beauty of life. The private gardens in the south of the Yangtze River, which simulate natural scenery, have the beauty of quiet and leisurely life. The inscription on the couplets and plaques of the gardens further deepens this aesthetic feature.
