The Houmuwu ding (Chinese: 后母戊鼎; pinyin: Hòumǔwù dǐng), also called Simuwu ding (司母戊鼎; Sīmǔwù dǐng), is a rectangular bronze ding (sacrificial vessel, one of the common types of Chinese ritual bronzes) of the ancient Chinese Shang dynasty. It is the heaviest piece of bronzeware to survive from anywhere in the ancient world.[1] It was unearthed in 1939 in Wuguan Village, Anyang, Henan, near Yinxu, the site of the last Shang dynasty capital.
