Popularized in 1998 when Premier
朱镕基 inspected dike repairs after the Yangtze floods and angrily called the substandard work
豆腐渣工程. The phrase has since become the standard Chinese term for any shoddy public-works project - the image is concrete that crumbles like soybean dregs (
豆腐渣, the leftover pulp from making tofu).
