On a stroll through a Chinese garden or park, one often finds oneself walking on footpaths of coloured pebbles arranged in patterns - a feature of Chinese landscape gardening.

These patterned paths are not designed by architects, but made by artisans from beginning to end. The paving of pebbles is a complicated job calling for skill and experience. First, lime mortar is spread out as the foundation layer, then the designs are outlined by means of plain and roofing tiles set in the mortar. On this is spread a special putty made of lime, wheat flour and tang oil, on which again are fixed the pebbles of various natural colours - green ones for plant leaves, black ones for animals' eyes, and so on. And the designs include all the usual subjects of traditional Chinese painting: landscapes, figures, flowers, birds, historical and popular legends.

The best of patterned footpaths in China are found in the Imperial Garden in the rear of the Forbidden City. The coloured pebbles there make up pictures under such familiar titles as "Magpie Announcing the Spring", "Dragon and Phoenix", "Cranes in Clouds", "Guan Gong Felling an Enemy", "Two Greybeards Watching a Game of Chess" and so forth, which symbolize good luck, victory, longevity and the like.

On the whole, patterned paths are found more often in parks and private gardens in the southern provinces than in the north. Prominant in this respect are the gardens in Suzhou, where the designs on pebbled paths display a wide range of subjects. Some are just geometric patterns, for instance, a square inside a circle like an ancient copper coin, signifying the old belief that "heaven is round and earth square". Others are in the forms of bats and cranes, Chinese symbols for good fortune and long life. Still others are patterned after the fishing net, expressing perhaps the general wish for affluent abundance.
