许生 / Xu Sheng (late-Han rebel)
Hanji 903 backfills Xu Sheng’s origin before the Hanji 905 suppression branch. The transcript renders him as 徐升, but the page keeps the existing canonical 许生 route because the Kuaiji rebel role matches Hanji 905. In this earlier notice, Xu Sheng rises in 会稽郡’s Juzhang county, proclaims himself Yangming emperor, attracts tens of thousands, and draws a court response through the Yangzhou inspector Zhang Ming and Danyang administrator Chen Yin.
许生 / Xu Sheng enters the wiki through Hanji 905 as the rebel described by the episode as a “妖贼” in the 174 CE Yangzhou-Danyang suppression campaign. The source does not develop Xu Sheng’s organization or program; his wiki role is to mark the local disorder that gives 孙坚 an early opportunity to recruit more than one thousand fighters and become visible to local authority.
The page is source-scoped to avoid overbuilding from a brief notice. Xu Sheng matters here less as a biography than as the crisis setting for 危机机会转化 and Sun Jian’s first armed-reputation branch.
