Bizi Mountain in Wufeng Village is located in the north of Wufeng Village, Cone Town, Changxing County. In March 2003, some hard pottery fragments were dug up on a hill called Bizishan in Changxing County, Huzhou City, Zhejiang Province due to foundation construction. Archaeologists finally discovered a large-scale aristocratic mound tomb during the Warring States period. What is even more gratifying is that they also excavated a musical instrument grave pit and unearthed more than a dozen complete ceramic chime instruments. This is the first archaeological discovery of the tomb pit in Zhejiang Province, which is of great significance to the study of Yue culture.
