When designing an indoor rockery fountain, we should pay attention to the size of the room and the ideas to be expressed as a whole. A simple rockery fountain is planned in the corner of the room, where a scene of Jiangnan water town is displayed and the leisurely artistic conception is interpreted. The small pool paved with pebbles is very small and natural, with many lotus flowers planted in the middle, which brings green tones. Coupled with the rockery, it highlights the artistic conception, and the realistic effect is like being outdoors, breathing fresh air and enjoying a carefree mood.
