Ts'ung Tube

??This ts'ung tube, carved from grayish-green jade with streaks of brown on one side, is round on the inside and square outside. The walls of the object are quite thin and it has a relatively large hole. With a short neck, the inside of the mouth and rim are round. The inside wall of the hole has been polished to a smooth surface, and the middle of each of the four sides protrudes slightly with a wide groove carved down the center.

??A later gilt bronze incense burner was made to fit inside and give this ts'ung tube a new function.

Traditional studies on ts'ung tubes in "Illustrated Study of Ancient Jades"

??...mention that what were once considered small ts'ung tubes were actually decorative wheel fixtures on the sedan chairs of rulers. Larger ones were the actual ts'ung tubes and served as jade ritual objects for venerating the earth deity.
