The jade Cong is made by pale jade, with bright sight, milky yellow in the gray and showing the gray-whithe markings in the ash. The Cong is a round cylindrical shape with a single segment and a slight protruding upper and lower crifices. A wide, straight shallow groove is formed in the middle of the four sides. The Cong was made for ceremony in the ancient times, so it was well made and standardized in shape. Thus it occupies a high cultural position in the ancient jade. Dimensions: Ht.5cm; Lg.7cm.
