Zhang Blade with Ivory Carrying Figures

This zhang blade was made of grayish white jade, roughly in the shape of a parallelogram. On each side were carved two symmetric groups of identical patterns. Each group has a kneeling human figure, two gyral lines and four parallel straight lines. Wearing a high hat and a long gown, the figure with a protruded nose, big eyes, broad mouth, square ears and cheeks, are keening on the ground, his left hand holding an object on his shoulder.
