许负 / Xu Fu (physiognomist)

许负 / Xu Fu enters the wiki through 《资治通鉴·秦纪》117-1｜啪啪打脸！历史上“爽文”的开山鼻祖 as the physiognomist consulted by 魏豹. She predicts that 薄姬 will bear a future royal or imperial son, a statement Wei Bao interprets as good news for himself.

The episode uses Xu Fu as a fate-reading hinge rather than as a full biography. Her prediction becomes famous in the source’s telling because it is fulfilled only after Bao Ji enters 刘邦’s orbit and gives birth to 刘恒, later Emperor Wen of Han.

This page is intentionally separate from 徐福, the Qin fangshi attached to immortal-island voyages. The two names are homophonous in pinyin but use different Chinese characters and belong to different story branches.
