Pond is an important element of Chinese classical landscape gardening. This paper combs the three forms of ponds in classical gardens: regular type, natural type and square and curved combination. Then, taking the gardening works of contemporary rockery craftsman FANG Hui as an example, this paper systematically discusses the relationship between natural type ponds and rockeries in medium and small scale gardening. FANG believes that small and medium scale gardens can be regarded as “gardens in the mountains”, while ponds can be regarded as “water in the mountains”. In this context, the conception and technology of pond water management are discussed and summarized from five aspects: “fixing water by mountain” “holding mountain by pond” “mountain and water integration” “the remnant of the mountain” and “lingering sound of water”. “Fixing water by mountains” determines the shape and size of water by the posture and scale of mountains. “Holding mountain by pond” is to make dry ponds and then stack rockeries in the construction process. “Mountain and water integration” reflects the depth and height of mountains by water. “The remnant of the mountain” is to create the revetment of ponds as the remaining vein of mountains. “Lingering sound of water” is to connect the garden water system with music, and the pond is treated as the lingering sound of the whole movement.
