??Carved from grayish-green jade with streaks of brown and white, this ts'ung tube is lustrous and has "sugar-brown and white" coloration. The width of both ends differs. The mouth was cut at an angle and is round inside but not outside. The neck is slightly elongated, and the four sides are flat. The wall of the hole inside is straight and lustrous.

??Jades referred to as "Ch'i-chia culture style" indicates that they are similar in many ways to archaeologically recovered jades from the Ch'i-chia culture, but they cannot be positively identified as such.
