capturing the full effect of the original paintings. The exact status of the later copies of reputed works by famous painters (many of whom are recorded in literature) before the 10th century is unclear. One example is a famous 8th-century painting from the Imperial collection, titled The Emperor Ming Huang traveling in Shu. This shows the entourage riding through vertiginous mountains of the type typical of later paintings, but is in full colour "producing an overall pattern that is almost Persian", in what was evidently a popular and fashionable court style. The decisive shift to a monochrome landscape style, almost devoid of figures, is attributed to Wang Wei (699-759), also famous as a poet; mostly only copies of his works survive. From the 10th century onwards an increasing number of original paintings survive, and the best works of the Song Dynasty (960–1279) Southern School remain among the most highly regarded in what has been an uninterrupted tradition to the present day. Chinese convention valued the paintings of the amateur scholar-gentleman, often a poet as well, over those produced by professionals, though the situation was more complex than that. If they include any figures, they are very often such persons, or sages, contemplating the mountains. Famous works have accumulated numbers of red "appreciation seals", and often poems added by later owners - the Qianlong Emperor (1711–1799) was a prolific adder of his own poems, following earlier Emperors. The shan shui tradition was never intended to represent actual locations, even when named after them, as in the convention of the Eight Views. A different style, produced by workshops of professional court artists, painted official views of Imperial tours and ceremonies, with the primary emphasis on highly detailed scenes of crowded cities and grand ceremonials from a high viewpoint. These were painted on scrolls of enormous length in bright colour (example below). Chinese sculpture also achieves the difficult feat of creating effective landscapes in three dimensions. There is a long tradition of the appreciation of "viewing stones" - naturally formed boulders, typically limestone from the banks of mountain rivers that has been eroded into fantastic shapes, were transported to the courtyards and gardens of the literati. Probably associated with these is the tradition of carving much smaller boulders of jade or some other semi-precious stone into the shape of a mountain, including tiny figures of monks or sages. Chinese gardens also developed a
