The famed terracotta warriors may have guarded the first emperor's tomb for centuries but they have been unable to fend off the mainland's invincible counterfeiters. Knock-off versions of the warriors were put on display at a library in Qingdao, Shandong province , last week, with visitors to the exhibition being charged 30 yuan each. The show, which featured nine life-size 'terracotta warriors' and about 100 smaller ones, even promoted itself with giant posters of state leaders viewing the genuine articles in Xian . Local authorities got wind of the deception and closed the show last Thursday, dumping the forged figures in the back of a truck and sending them to be used as landfill, China Central Television reported. Visitors to the library's show seethed at the institution's duplicity. 'They are deceiving the public,' one visitor fumed. 'If these are copies, they should say so.' Staff employed by the organiser of the real touring exhibition, the Terracotta Warriors Museum in Xian, Shaanxi , were appalled by the shoddy reproductions. 'The show is so foul because the wares on display are badly made and have damaged the reputation of the real warriors,' museum representative Zhu Xuewen said. 'Visitors cannot tell what real heritage is. There are too many counterfeit terracotta warriors and we are only a local museum without the strength to investigate illegalities.' It is not the first time forgers have sought to pass off fake versions of the Qin dynasty burial statues as the real thing. Two years ago, a similar exhibition of about 400 fake terracotta warriors was held in the Guangdong city of Huiyang . The real exhibition of 81 figures is now in Xiamen , Fujian province , and is due to move on to the Qingdao Museum next week.
