The nine main bas-reliefs are the large-size pieces (panels) carved in marble and originally painted in gold (gilded), red and brown pigments, on the exterior of the front right and left walls, and on the interior of the right, rear and left walls. They can be divided into two groups: the first group consists of four pieces, which may depict some scenes from Yu Hong's daily life; the rest may represent his afterlife in paradise. Each panel is divided into a larger upper part and a smaller lower part.
