In February 2007, the State Administration of Cultural Heritage approved the excavation of the Grand Baoen Temple ruins.

Cultural relics made from materials including gold, silver, bronze, crystal, glass, agate and silk were discovered at the site.

Archaeologists said those cultural relics were well preserved as they were buried nearly seven meters underground in an iron container. And around 100 silk fabrics excavated from the site are believed to have been donated by Buddhists to the temple.
