Tea unearthed from the 2,100-year-old tomb of an emperor will be displayed at a museum in northwestern China this week.

Zhang Yun, deputy director of the Hanyang Mausoleum Museum in Xi'an, capital of Shaanxi province, says that the tea, recently recognized as a Guinness World Record for being the world's oldest, will be exhibited at the museum starting on Wednesday.

He says the tea was mixed with grains when it was first discovered in 2005 at the Hanyang Mausoleum. The site was the graveyard of Emperor Jing (188-141 BC), father of Emperor Wu, whose reign ushered in one of the most prosperous periods in Chinese history.
