The silk painting portrays the prosperous commercial street in the short interior city of Beijing in Yuan Dynasty, across which runs the canal from east to west under the Shimen Bridge of Di’anmen. On both sides of the street extend a variety of boutiques such as a store of pickles named Big Red Gourd, teashops，etc. This silk painting is hand-made using five kinds of weaving materials: twill-weave silk, gauze, silk, satin and tough silk. In comparing them, the twill-weave silk feels thicker than the other fabrics; the silk feels thinner and softer and is brighter and smoother; the gauze is thinner, softer, lighter and finer than silk; the satin products are of the most sophisticated technology and the most advanced art compared with all of its counterparts, for it is brilliant, lustrous, soft, smooth and gives out a vertical sense; and the weaving products made of the tough silk are of light quality and they are neat and hard to bent. In ancient times, these silk materials were reserved as royal fabrics and therefore they were rarely known to the public.
