Archaeologists in northwest China's Shaanxi Province said on Saturday they had unearthed 11 bamboo containers that date back to more than 2000 years, containing what is believed to be delicacies.

The containers were discovered in a small room adjacent to the main tomb believed to belong to a daughter-in-law of Zhang Anshi, a high-ranking official in Western Han Dynasty (202 BC- 9 AD), said Zhang Zhongli, vice dean of the provincial archaeological research institute.

"We saw some fungus-like things and some animal bones in the bamboo containers through an endoscope. Since the tombs are often designed to mirror the life of the tomb owners, the food probably was delicacies," said Zhang.

A lacquer wooden box was also found in the room. The excavation is suspended until the woodware and bamboo relics are protected.
