"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 B.C.), Qin (221-206 B.C.), Han (206 B.C.-A.D. 220) and Tang (618-907 A.D.) 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)."

　　"This exhibition aims to introduce China's vigorous and everlasting culture," Tan Shengguang, the exhibition curator, told Xinhua.

　　"Fine Chinese traditions have been passed down generation after generation. We hope the exhibition can help visitors find their roots and greater self-confidence," Tan added.

　　The exhibition catalog, containing 648 pages and over 1,000 images, was also recently published, selling out in just 20 hours.
