Jiang's family recently donated this well-known piece to the China National Academy of Painting, along with dozen of the artist's tools and documents.

Liu Wanming, director of the China National Academy of Painting, says the painting is a landmark of Jiang's career and a classic piece of modern Chinese art.

He says it displays the artist's shrewd observation of society and deep concern for people, expressed via fine techniques, and will continue to inspire artists to address the needs of their times.
