???????Caves 7 and 8 of the Yungang Grottoes in Datong City, north China's Shanxi Province are revealing renewed glamor after five months of conservation and restoration through digital technologies.

The two caves were temporarily closed on May 13 for data collection and structural assessments by the Yungang Grottoes Research Institute, and reopened to public on Oct 27.
"The grottoes are incredibly beautiful and enchanting. We feel a deep attraction when we look at them," said Zhang Wanting, a visitor.
Located in the central area of the grotto complex, Caves 7 and 8 are the oldest double caves excavated during the mid-period of the Yungang Grottoes.
Built under the design and direction of Emperor Xiaowen of the Northern Wei Dynasty (386-534 A.D.), these large-scale caves are considered representative works of the era.
"Caves 7 and 8 were the first double caves excavated during the mid-period of the Yungang Grottoes' construction. The structure of the two caves that we see today exemplifies a classic Buddhist temple cave, featuring a distinct separation between the front and rear chambers, reminiscent of the palace-like architectures in China," said Chen Chen, a guide at Yungang Grottoes.
Cave 7 is home to six exquisitely beautiful figures, while Cave 8 is notable for a Bodhisattva with folded hands and exposed teeth.
"In 1933, [renowned architect couple] Liang Sicheng and Lin Huiyin visited Cave 7 and saw these six celestial beings. Therefore, this cave is known as the 'Cave of the Six Beauties' by later generations," said Chen.
Boasting 45 major caves, the 1,500-year-old Yungang Grottoes were listed as a UNESCO World Heritage Site in 2001.
