Archaeologists have discovered a bronze kettle containing 2,000-year-old liquor from an excavation site in Shaanxi, China. The kettle contained about 300 ml of liquor and its opening was sealed with natural fibres, a researcher said. The kettle was among 260 items, including a sword and a turtle plastron shell, unearthed from commoners' tombs of the Qin Dynasty (221-207 BC).
