Contributed by Rosetta Marantz Cohen / Rare among contemporary artists, Hung Liu, who died in 2021, chronicled the trauma experienced by the Chinese diaspora in the aftermath of the Cultural Revolution. Her paintings, currently on view at Ryan Lee, vividly depict a female artist’s efforts to reconcile the terror of China’s recent past and the “otherness” she experienced after her emigration to the United States. The exhibit seems especially poignant now as questions about homeland, memory, and trauma resonate with such immediacy.
