The "Sakuteiki" recommends several possible miniature landscapes using lakes and streams: the "ocean style", which features rocks that appear to have been eroded by waves, a sandy beach, and pine trees; the "broad river style", recreating the course of a large river, winding like a serpent; the "marsh pond" style, a large still pond with aquatic plants; the "mountain torrent style", with many rocks and cascades; and the "rose letters" style, an austere landscape with small, low plants, gentle relief and many scattered flat rocks.
