Milefo is depicted wearing monastic robes in turquoise, red, and aubergine, blending into the rocky landscape.
His face, torso, hands, and feet, all the fleshy parts, are made of chiseled and gilded bronze. He holds a rosary in his right hand and carries a canvas bag on his back.
The wooden frame is carved with floral scrollwork.

The Buddha Milefo (弥勒佛) is the Chinese version of the bodhisattva Maitreya, the Buddha of the future in the Buddhist tradition. According to teachings, Maitreya will appear on Earth at a time when the teachings of the historical Buddha, Gautama, will have disappeared, in order to restore the Dharma (Buddhist law). In China, Milefo is commonly depicted in a very distinctive and popular form, that of a smiling, bald, pot-bellied monk, often dressed simply and carrying a large cloth bag. This image is inspired by a legendary 10th-century monk named Budai (布袋), who was later considered an incarnation of Maitreya. A symbol of joy, prosperity, generosity, and benevolence, Milefo is a much-loved figure in Chinese popular culture, frequently depicted in Buddhist temples, homes, and businesses to attract happiness and fortune. Unlike Gautama Buddha, Milefo embodies the promise of a happy future and spiritual renewal to come.
