Introduction to Buddha statues: The two Eastern Wei grottoes and the three Northern Qi grottoes are square caves with three walls and three niches. The Eastern Wei statues all have three statues, namely Sakyamuni on the front wall, Maitreya on the left wall, and Maitreya on the right wall. Amitabha's third generation Buddha. In the Western Wei Dynasty, it was changed to five statues, and the sitting Maitreya Buddha was changed to the Maitreya Bodhisattva sitting cross-legged. The statues of the Eastern Wei Dynasty are thin, with simple and concise techniques, and they are still in the style of "beautiful bones and clear images". The Northern Qi Dynasty statues have reduced the sense of movement and focused on the carving of the physical structure, and the sculpture language has been perfected. At the same time, you can also see the attention paid to the architectural structure in the shape of the niches and caves, which quite accurately reproduces the original appearance of the wooden buildings at that time.
