t'sung

CONT: Lors du culte de la nature, les plus importants étaient les six jades rituels : «Pour rendre grâces au ciel, il faut [...] à la terre un t'sung jaune [...]»

OBS: Chinese texts refer to them as symbols of the earth and, along with the pi, which symbolizes heaven, they are often found in tombs and used in ceremonies. Their original meaning is somewhat obscure, but it has been suggested that they might have been female fertility emblems encasing a male phallus.
