The immense collection of the National Art Museum of China includes several pieces that are considered iconic. Among them is Refugees, Jiang Zhaohe's compassionate depiction of a people and a country suffering during the War of Resistance Against Japanese Aggression (1931-45).

The public doesn't often see this ink painting, completed in 1943, as it is 12 meters long and is too delicate to display.

Universal Harmony, an ongoing exhibition at the NAMOC, is a rare opportunity to see the landmark painting, which is on show together with dozens of other artworks from different periods by members of the China Democratic League.
