Origin from a Place of Residence
Another account holds that the surname may have arisen from residence in a place called “阬”; the source further places the former site twenty-six li east of present-day Linru County, Henan. This account is quoted from the Xingshi Kaolue, and the source gives no further administrative history or later migration record.
