His father Efu (閼父) served as taozheng (陶正), the official in charge of the manufacture of pottery, for the Zhou state.
[2][3] After King Wu conquered the Shang dynasty to establish the Zhou dynasty in 1046/45 BC, he enfeoffed the descendants of three ancient sage kings in the newly conquered land, known as the San Ke (三恪, "Three Reverent States"), and Man was enfeoffed at the state of Chen, with its capital at Wanqiu, in modern Huaiyang County, Henan Province.
[8] Duke Hu's tomb was said to be made of iron and buried under water near the Dragon Lake in Huaiyang County.
Archaeologists have found Western Zhou era pottery shards and Warring States-era roof tiles in the area.
