An artist's rendition of the Shaanxi Pavilion [en.expo2010.cn]

The search is on for two people from Shaanxi Province who most resemble Emperor Xuanzong of the Tang Dynasty (618-907 AD) and his consort Yang Yuhuan. They'll greet visitors to the Shaanxi exhibition at the World Expo.

The Emperor Xuanzong should be taller than 175 centimeters and younger than 45 years old, while Yang Yuhuan must be under 30, at least 165cm tall, and weigh at least 50kg.

The actors will stand in front of the pavilion with two robots made to resemble the emperor and his wife, officials said.

The reward for the lucky actors: 10,000 yuan (US$1,465).
