Here is the exhaustive biography of Lei Bo (雷薄, Lôi Bạc) (? – ?), an officer of Yuan Shu (袁术, Viên Thuật) who deserted to Mount Qian (灊山) with Chen Lan (陈兰, Trần Lan), incorporating historical notices and Romance of the Three Kingdoms. Modern notes often identify him with Lei Xu (雷绪, Lôi Tự) / Lei Pu (雷蒲) — treat that as a debated identity, not proven kinship.

Biography & Historical Record

Lei Bo came from the Yangzhou / Lujiang sphere and served Yuan Shu. After Yuan Shu’s Zhong pretender regime collapsed under successive defeats, Lei Bo and Chen Lan occupied Mount Qian in Lujiang as independent leaders. In 199, when the fleeing Yuan Shu sought their stronghold, they refused him refuge; Yuan Shu turned aside and soon died of illness and exhaustion. Primary notices stop at that refusal. A later figure matching Lei Xu was reconciled through Liu Fu (刘馥, Lưu Phức), briefly served under Cao Cao (曹操, Tào Tháo) / Xiahou Yuan (夏侯渊, Hạ Hầu Uyên) in Lujiang, then led several thousand men to Liu Bei (刘备, Lưu Bị); if Lei Bo = Lei Xu, that is the after-career — sources do not narrate it under the name 雷薄.

Role in Romance of the Three Kingdoms

Under Yuan Shu: Lei Bo serves under Ji Ling (纪灵, Kỷ Linh) against Liu Bei at Xiaopei, and commands one of the seven armies in Yuan Shu’s push on Lu Bu (吕布, Lã Bố) and Xuzhou, clashing toward Langye with Zhang Liao (张辽, Trương Liêu) and Zang Ba (臧霸, Tang Bá).

Desertion: Disgusted by Yuan Shu’s arrogance after the Imperial Seal, Lei Bo and Chen Lan quit for a mountain fortress (Mount Song / Qian). Their departure weakens Yuan Shu’s remaining strength.

Ch. 21 — Blocking the flight: When Yuan Shu’s remnants flee north, Lei Bo and Chen Lan bar the road, seize baggage and provisions, and force him aside. History: refusal of refuge is attested; the full novel robbery of the baggage train is literary heightening. The novel does not continue Lei Bo’s story afterward.

Lei Bo (雷薄, Lôi Bạc) — Historical & Literary Timeline

c. 197–199 AD — Yuan Shu

Subordinate general

Serves Yuan Shu’s Huainan / Zhong regime. Novel: Xiaopei under Ji Ling; seven-army war against Lu Bu / Xuzhou.

199 AD — Mount Qian

Desertion and refusal

With Chen Lan occupies Mount Qian / Song. History: refuse the fleeing Yuan Shu. Novel: also seize baggage on the northern road (Ch.21).

c. 200–209 AD — Lei Xu path (debated)

If identical with Lei Xu

After Mount Qian is suppressed: Liu Fu’s mediation → brief Cao Cao / Xiahou Yuan service → transfer with several thousand men to Liu Bei. Not narrated under the novel name Lei Bo.

Historical Note

Lei Bo’s solid historical footprint is the Mount Qian desertion with Chen Lan and the refusal that helped finish Yuan Shu. The novel supplies earlier battlefield colour and a sharper Ch.21 robbery. Equating him with Lei Xu explains a later Cao Cao → Liu Bei arc but remains a scholarly identification, not a family relationship and not a plot line in the novel.

For overview notes, see Lei Bo on Wikipedia.

Key Relationships

Family

No father, mother, spouse, or children are named for Lei Bo (雷薄, Lôi Bạc) in novel or history. Lei Xu (雷绪, Lôi Tự) is a possible same person (identity debate), not an attested relative — see Other.

Friends

Chen Lan (陈兰, Trần Lan): Closest comrade. Novel & history: desert Yuan Shu together, co-hold Mount Qian / Song, and jointly refuse (novel: also rob) the fleeing pretender in 199. The bond is partnership in revolt, not kinship.
Ji Ling (纪灵, Kỷ Linh): Novel: superior in Yuan Shu’s attack on Liu Bei at Xiaopei; Lei Bo fights in that chain of command. History: Ji Ling is Yuan Shu’s chief general; Lei Bo is not individually tied to him in chronicle lines beyond shared Yuan Shu service.

Enemies

Yuan Shu (袁术, Viên Thuật): Former lord, then target of desertion. History: refused refuge at Mount Qian (199). Novel: desertion after the Seal, then Ch.21 roadblock and seizure of baggage — the act that seals Yuan Shu’s collapse in the story.
Liu Bei (刘备, Lưu Bị): Novel only (early): opposed under Ji Ling at Xiaopei while Lei Bo still serves Yuan Shu. History / Lei Xu path: if Lei Bo = Lei Xu, he later joins Liu Bei — so treat early hostility as Yuan Shu–period novel combat, not a lifelong enmity.
Lu Bu (吕布, Lã Bố): Novel: Lei Bo appears in Yuan Shu’s multi-army pressure on Lu Bu / Xuzhou (with fighting toward Zhang Liao and Zang Ba at Langye). History: no personal Lei Bo–Lu Bu duel notice.

Other

Identity: Lei Bo ↔ Lei Xu (雷绪, Lôi Tự) / Lei Pu (雷蒲): Many modern notes equate them. Under that reading, after Mount Qian: Liu Fu (刘馥, Lưu Phức) mediates, brief service under Cao Cao / Xiahou Yuan (夏侯渊, Hạ Hầu Uyên), then several thousand men to Liu Bei. Keep as one debated identity — never list Lei Xu under Family.
Cao Cao (曹操, Tào Tháo): Suppresses Huainan / Mount Qian banditry. If Lei Xu: intermediate lord before the transfer to Liu Bei. Novel Lei Bo: no continued service under Cao Cao after Ch.21.
Zhang Liao (张辽, Trương Liêu) / Zang Ba (臧霸, Tang Bá): Novel: opponents or opposing-sector commanders in the Langye / Xuzhou fighting while Lei Bo still serves Yuan Shu.
Mei Cheng (梅成, Mai Thành): Huainan / Mount Qian–sphere insurgent often named with Chen Lan in later suppression notices; plain text (no site post). Useful same-arc bandit context, not a proven sworn brother of Lei Bo.
Novel vs history on Yuan Shu’s end: History = closed gates / refused refuge. Novel = bars the northern road and seizes provisions (Ch.21). Both end Yuan Shu’s last hope; only the novel adds the baggage seizure.

In Novel

Chapters 16–17

Lei Bo (雷薄, Lôi Bạc): Officer of Yuan Shu (袁术, Viên Thuật); serves under Ji Ling (纪灵, Kỷ Linh) against Liu Bei (刘备, Lưu Bị) at Xiaopei; later commands one of the seven armies against Lu Bu (吕布, Lã Bố) / Xuzhou, fighting toward Zhang Liao (张辽, Trương Liêu) and Zang Ba (臧霸, Tang Bá).

Chapter 21

Lei Bo (雷薄, Lôi Bạc): With Chen Lan (陈兰, Trần Lan) deserts Yuan Shu for Mount Song / Qian; when Yuan Shu flees north they bar the road, seize baggage, and force him aside. Not mentioned again. History: refusal of refuge attested; full baggage seizure is novel heightening.

In History

Summary

Lei Bo (雷薄, Lôi Bạc) deserted Yuan Shu with Chen Lan, held Mount Qian (灊山), and in 199 refused the fleeing pretender refuge. Often identified with Lei Xu / Lei Pu — debated identity, not kinship.
