The 16th to 20th caves in the Datong Yungang Grottoes Scenic Area are the earliest caves opened in Yungang. Because it is the famous high monk and the scorpion preside over the construction, it is called the "Wu Grottoes". This is the first phase of the project of Yungang Grottoes. The center of the five grottoes is carved with huge statues of Buddha, symbolizing the five emperors of the Northern Wei and Wu Dynasty. The main dignitaries of the caves of the 'Five Grottoes' are: the 16th Grotto is the Buddha statue of the fearless seal, the 17th Grotto is the Buddha statue of the foot, the 18th Grotto is the Buddha statue of the fearless seal, and the 20th Grotto is the Buddha statue of the Zen-printed seal. The Wu Grottoes reflect the special Buddhist culture of the early Northern Wei Dynasty, and the five Buddhas represent the Buddha while also symbolizing the specific emperor individual. This particular Buddhist image never appeared in India or other advanced Buddhist areas, and the excavation of the Wu Grottoes reveals the creation of "Chinese Buddhism" unlike Indian Buddhism.
