Introduction to the iron cast Buddha head: The Buddha head located in the heart chamber of the pagoda is 6.8 meters high, 3.8 meters wide, 16 meters in circumference and weighs 15 tons. It is cast from pig iron in one go. The statue is dignified in shape, with a kind face, plump cheeks, ears close to the shoulders, and a very vivid charm. Judging from the modeling style of the Buddha's head, it not only inherits the traditional techniques of statues in the Northern Wei Dynasty, but also integrates the characteristics of the sculpture art of the Southern and Northern Dynasties. It can be said to be a masterpiece of iron-cast Buddha statues.
