*The handscroll A Thousand Li of Rivers and Mountains was painted by Wang Ximeng in the Northern Song dynasty. It is ink and color on silk, measuring 51.5 centimeters in height and 1,191.5 centimeters in length, and is now held by the Palace Museum. It is the only surviving work known to be by Wang Ximeng. The painting depicts mountains, rivers, waterfalls, bridges, houses, boats, and people. Its handscroll format uses multiple viewpoints, so the scene changes as the scroll is unfolded. A colophon by Cai Jing records that Wang Ximeng was eighteen when he received instruction from Emperor Huizong and completed the painting in less than half a year.
