Archeologists unearthed some yellow liquid inside a bronze vessel, which is in the shape of a garlic bulb at Xi'an, capital of northwest China's Shaanxi Province.
The vessel, belonging to the early Han Dynasty from 206 BC to 220 AD., is approximately 30 cm tall with a long-neck, round belly.
"Such vessels were usually used to keep liquors, but we could hardly tell what it is before testing," said Xu Yongchu, an expert with Shaanxi Provincial Archeology Research Institute.
The vessel was unearthed in a six by four meter tomb, which is possibly owned by a ranking official, and it is among a couple of tombs belonging to the early Western Han Dynasty, Xu acknowledged.
The cache of relics also included cocoon-shaped pottery kettles, food-cooking earthen utensils, pottery jugs, pottery cauldrons, bronze mirrors and bronze combs.
Ancient liquor belonging to the imperial Han Dynasty has been unearthed in Shaanxi Province before the latest finding.
