The first stop to enter the Yungang Grottoes Scenic Area is the Yu Square, located next to the tourist center of Yungang Great Scenic Area. The Yungang Grottoes are divided into three phases of construction. The first phase of the project was built by the Yu mage to repair five caves, known as the "Yunwu Grottoes". The five Buddhists in these five caves symbolize the five emperors of Northern Wei, so this square was built to commemorate the founder of Yungang Grottoes, the high monk. But his life was in a changing era, he with a great fearlessness, launched a series of work to revive Buddhism, whether in politics, economics, education, art or translation, Buddhism to a scene of recovery and prosperity, can be said to be the Northern Wei Dynasty Fu Buddha generation law will. In Yungang Grottoes, he left his good memories of Buddhism, leaving behind his Zen and enlightenment, that is today's magnificent Wucao. In the center of the square is a statue of Master Xu, which is itself an artwork, and the sculpture is from the hand of Wu Weishan, a famous sculpture master and director of the Chinese Art Museum. Entering the grotto and looking up at the high monk, as if watching him looking at the visitors after the millennium, listening to the different names that everyone called him, wide sleeves and comfortable, showing a remarkable smile, making people calm and peaceful.
