"Everlasting Like the Heavens," a 99-day-long exhibition held at Tsinghua University Art Museum, concluded Tuesday.

The exhibition features cultural relics from the Zhou (1046-256 BC), Qin (221-206 BC), Han (206 BC-AD 220) and Tang (618-907 AD) dynasties.

It opened on Sept 10, with the Shaanxi Provincial Cultural Heritage Administration and Tsinghua University as hosts. In total, 311 pieces were chosen from museums from Northwest China's Shaanxi province, with another four coming from Tsinghua's collection.

The showcased items reflect the gleaming spirit of these flourishing ages during which many of China's traditions were developed and shaped, organizers said. Several highlights of the exhibition include a hezun (bronze wine vessel) that is the oldest known relic with characters reading "Middle Kingdom (China)."
