A big copper tree leading to the sacred tree

Rosen, a British scholar, wrote in the book The Secret of Ancient China that the bronze tree in Sanxingdui is made of precious materials, that is, it is cast in bronze, which may imply that it represents the immaterial world outside the world. Sanxingdui copper tree shows us a sky-high theme with its trunk, birds, flowers and the sun on the sacred tree for people to imagine. On the branches of the bronze tree, you can clearly see some perforations for hanging utensils. Archaeologists found some small bronzes from the object pit of Sanxingdui. These bronze sounders may be hung on copper trees. Three thousand years ago, when the wind blew through Sanxingdui, people in the whole kingdom could hear the music played by the swaying and collision of metals. The crisp sound proves that a great bronze age reached its peak in Sichuan Basin. Casting many sacred trees with bronze required great determination at that time, because it was a very huge and complicated manufacturing process. Judging from the casting technology of bronze sacred tree, the craftsmen of Sanxingdui used the most advanced technology and means at that time, as if they had completed a number of immortal ritual vessels. Perhaps, the maker of the sacred tree thinks that "production completion" is not the ultimate goal, and it can only be truly completed if it is completely crushed according to the ultimate sacrifice ceremony.
