Socialism Good is a site-specific work. Following research related to the vegetation at Cass Sculpture Foundation, Zheng Bo chose to use red, yellow and green plants to form a popular political slogan banner from China in the 1950s: ‘Socialism is Good’. During the winter months, the characters of the slogan blurred as the plants withered. In the spring, legible slogans revealed themselves again as the plants regenerated. These plant-based installations bearing political slogans were common features of Tiananmen Square, often appearing as part of the National Day celebrations before the 1990s, as a vehicle for political propaganda.
