The Suzhou Couple’s Garden is a garden that retains the remains of the early Qing Dynasty yellow stone rockery and was extended by Shen Bingcheng of Huzhou in the late Qing Dynasty. The purpose of this paper is to discuss in detail the landscape design of the Yellow Stone Rockery in the East Garden of the Suzhou Couple’s Garden, revealing its unique horticultural art and spatial layout. The study starts from the yellow stone rockery remains, with the help of the plan, elevation, section, current situation of the East Garden of the Couple’s Garden and related documents, excavates the deep connection between yellow stone rockery and “Giant Roach” landscape, and analyses the layout of the landscape garden of “four sides of a mountain”, the landscape pattern of “mountain perched on the side of the pool”, the spatial characteristics of “fewer than many”, and the highly linearized architectural pattern. The study helps to further explore the characteristics of Ming and Qing gardens’ “pictorial” mountain and rock landscape design, providing historical references and theoretical significance for the design and study of rock landscapes in modern gardens.
