Building on simpler predecessors and concepts, the first actual ever-normal granary was built in 54 BC. Its name was "Chang-ping can", and its translation provides the English name. It was promoted by Wang Anshi during the Northern Song period and thereafter. Another well-known example of ever-normal granaries is during the Sui dynasty in China (seventh century AD). The system was used in the Han, Jin, Sui and Tang dynasties. When the system collapsed during the An Lushan Rebellion, massive famine and even cannibalism broke out. Although it was not the first to implement this concept, nowhere else in the world was such a system practiced at such a large scale and long span of time. In the Qing dynasty (1644-1911) the government established a nation-wide state granary system, which involved a total of 2.2-3.3 million tonnes of grain, the largest such system in the world. Over 100 million lives were saved by the grain distribution scheme. In the 1850s Taiping Rebellion the granary system was destroyed and never fully restored.
