     Although Wu Huifei was only a concubine (妃子) of Tang Xuanzong (AD 685-762), the sixth

emperor of the Tang Dynasty, her influence was far greater than most in her position.

     Historians say that the ruler loved her so much that, in AD 724, he banished his wife and made

Wu a royal concubine.

     "Although she was only a concubine, she was treated as an empress with palace etiquette (礼节),"

explained Shi Xiaoqun, director of relics collection for Shaanxi History Museum. "Tang Xuanzong even

wanted to make her his empress but was opposed by the ministers."

     The emperor had thousands of concubines in his palace in Chang'an (now called Xi'an, capital of

Shaanxi province) but, according to Shi, he only loved Wu, the mother of seven of his children.

     Wu died in the December of AD 737 at the age of 38 and was buried in Jingling Mausoleum. She

was given the title Empress Zhenshun after her death.

     "It's rare for a concubine to be given so much posthumous (死后获得的) honor in the history of

Chinese feudal (封建) society," said Liu Daiyun, research director at the Shaanxi Archaeological

Research Institute.

     Her tomb -53 meters wide by 56 meters long - is located in the west of Pangliu village, which is

part of Xi'an's Chang'an district.

     The recovered sarcophagus (石棺) is 4 meters long, 2 meters wide and 2 meters tall and is

decorated with flowers and maiden figures, which archaeologists say is a rare cultural relic of high

scientific, historical and artistic value. In ancient times, a sarcophagus was used to house wood coffins

in order to preserve the body of the noble person.

     "I knew it was precious but I didn't know it was so beautiful," said Han Qinglong, who headed the

team that brought the relic back to China four years after it was stolen and sold abroad by tomb raiders (盗墓者).
