Yungang Grottoes, imposingly carved out of a mountain side and about 1 km in width, is one of the four famous treasure troves of Chinese grotto art.  Located at the southern foot of Wuzhou Mountain, the grotto area was excavated along the mountain, imposingly stretching 1 kilometer with rich contents. Covering over 18,000 square meters engraving area, there are existing 45 main caves, 209 subsidiary caves, more than 1,100 niches, and more than 51,000 stone statues, among which the largest statue measures 17 meters and the smallest only 2 centimeters. One of the largest stone caving art treasury famous both home and abroad, the Yungang Grottoes was inscribed as a key cultural relic under the state protection in 1961, a world heritage site in 2001, and a 5A national Scenic Area in 2007.

The Hanging Temple, also called the Hanging Monastery,it is in Hunyuan County, Datong, Shanxi Province. Built over 1,500 years ago, and suspended on the cliffs of Hengshan Mountain, about 50 meters above the ground, the Hanging Temple is a truly amazing feat of engineering and one of the world's forgotten wonders. The building's features can be summarized as "strange, cliff and ingenious". Strange- Looking up Hanging Temple in distance, it seems as an exquisitely carved anaglyph set in steep bluffs; if you observe it closely, it looks as if it is flying to the sky. Cliff- A total of 40 cabins were suspended, which seems to be supported by several wooden columns. In fact, some columns didn't bear the weight.
