The National Museum of China in Beijing is hosting an exhibition titled "Rice, Origin, Enlightenment" to highlight the cultivation history of the humble grain. The show displays nearly 200 artifacts from the early, middle and late phases of Shangshan Culture, including the earliest carbonized rice in China. The Shangshan Culture was discovered in 2000 during an excavation in Pujiang County of east China's Zhejiang Province. It dates back to between 11,400 years and 8,600 years and archaeologists believe that the sites house the oldest examples of cultivated rice.
