Quick answer：

A three-level artificial rockery fish pond is a traditional Chinese garden feature that combines the aesthetics of rock formations with aquatic environments. It typically consists of three tiers of rock formations, each at a slightly lower level than the one above, creating a natural-looking waterfall. The pond is designed to accommodate fish and other aquatic life, and the rock formations are often adorned with plants and moss, enhancing the serene and harmonious atmosphere of the garden.
