TAIYUAN, May 28 (Xinhua) -- An exhibition featuring 4,431 recovered stolen cultural relics, mostly bronzeware from the Shang and Zhou Dynasties, was held at the provincial museum of north China's Shanxi Province.

The province earlier launched a campaign to crack down on the theft of ancient tombs, architecture, stone carvings, frescoes and sculptures.

So far, the province has caught 296 suspects in cultural heritage-related crimes and solved 230 such cases.

A total of 29 gangs were caught and 2,525 items were retrieved in Shanxi, according to the provincial public security department.

Shanxi is home to 452 cultural relics sites under state-level protection and more than 28,000 ancient architectural sites -- the highest of all provincial regions.

The exhibition is expected to last until August.
