What’s the most “mind-blowing” artifact at Sanxingdui?

The "bronze sacred tree" (青铜神树, qīngtóng shénshù) is unmissable. At 3.96m tall (13ft), it's the largest ancient bronze artifact ever found in China. It has 9 branches, each with a bird (likely representing the sun), a coiled dragon at its base, and a phoenix at the top. Its symbolism—connecting heaven, earth, and the underworld—feels almost otherworldly. Stand next to it, and you’ll feel tiny—it’s shocking to think they built this 3,000 years ago.
