Introduction
Peng Yang (simplified: 彭羕, traditional: 彭羕, pinyin: Péng Yàng), courtesy name Yongnian (永年), was a Shu Han official from Guanghan Commandery who rose to prominence after Liu Bei’s takeover of Yi Province. Recommended by Pang Tong and Fa Zheng, he served as Chief Clerk for the Army (治中從事) and was used to convey military orders. His arrogance and Zhuge Liang’s distrust led to his demotion to Administrator of Jiangyang (江陽太守). After he made intemperate remarks to Ma Chao—including calling Liu Bei “old soldier” and implying he and Ma Chao would “settle the realm” inside and out—Ma Chao reported him. Peng Yang was imprisoned and executed at age thirty-seven, despite a letter to Zhuge Liang explaining his words.
Biography
Early life and disgrace under Liu Zhang
Peng Yang was from Guanghan (广汉), Guanghan Commandery. He was tall (eight chi) and imposing in appearance, but proud and dismissive of others; he respected only his fellow commandery man Qin Mi (秦宓) and recommended Qin Mi to the Administrator Xu Jing.
In Yi Province he held only a low post as book-keeper (书佐). Others slandered him to the Governor of Yi Province, Liu Zhang, who had him punished by “crowning and clamping” (髡钳—shaving head and beard and wearing fetters) and reduced to convict labour.
Joining Liu Bei and rise to治中從事
When Liu Bei entered Shu and advanced north along the river, Peng Yang wanted to offer his services. He went to see Pang Tong. Pang Tong did not know him and had guests, but Peng Yang went straight to Pang Tong’s couch, lay down, and said he would talk properly once the guests left. After they left, Pang Tong sat with him; Peng Yang had Pang Tong share food first, then they talked and he stayed for a day and a night. Pang Tong thought highly of him, and Fa Zheng had long known him, so both recommended him to Liu Bei.
Liu Bei also found him unusual and repeatedly had him convey military instructions to the generals. He performed to satisfaction and was increasingly favoured. After Chengdu was secured and Liu Bei took the title Governor of Yi Province, Peng Yang was promoted to Chief Clerk for the Army (治中從事).
Arrogance, Zhuge Liang’s distrust, and demotion
Having risen from obscurity to a position above others in the province, Peng Yang became openly arrogant and full of himself. Zhuge Liang received him politely in public but did not approve of him in private and more than once told Liu Bei that Peng Yang was “broad in heart and ambition and hard to keep safe.” Liu Bei, who trusted Zhuge Liang and had observed Peng Yang’s conduct, gradually distanced him and transferred him out as Administrator of Jiangyang (江陽太守).
Conversation with Ma Chao and execution
When Peng Yang learned he was to be sent to the outer commandery, he was unhappy. He went to see Ma Chao. Ma Chao asked why someone of his talent, whom the lord had compared to Kongming and Xiaozhi (Fa Zheng), was being sent to a small commandery. Peng Yang said: “That old soldier is absurd—what more is there to say!” and added: “You take the outside, I’ll take the inside; the realm is not hard to settle.” Ma Chao, as a recent defector, was always on edge; he was shocked and said nothing. After Peng Yang left, Ma Chao reported his words in full. Peng Yang was arrested and handed to the authorities.
In prison Peng Yang wrote to Zhuge Liang. He admitted having called Liu Bei “old” in a moment of drink and resentment, but insisted that by “you outside, I inside” he had meant only that Ma Chao should campaign in the north and he would assist at court against Cao Cao, with no disloyal intent. He expressed regret and asked Zhuge Liang to understand his true heart. He was still put to death, aged thirty-seven.
Personality and traits
Abilities and pride
Peng Yang was capable and imposing in appearance, and his recommendation by Pang Tong and Fa Zheng and his effective delivery of military orders show he had talent. The same sources describe him as “proud by nature and often contemptuous,” and only respectful of Qin Mi. That pride and lack of restraint led to his demotion and then to his fatal remarks to Ma Chao.
Zhuge Liang’s assessment
Zhuge Liang’s private view was that Peng Yang was “broad in heart and ambition and hard to keep safe,” which influenced Liu Bei to demote and then remove him from the centre.
Political achievements
Service under Liu Bei
Peng Yang’s main contribution was conveying military orders and instructions to the generals during the takeover of Yi Province, which Liu Bei found satisfactory. He also recommended Qin Mi to Xu Jing in a letter praising Qin Mi’s virtue and learning.
Relationships
Lord and colleagues
Peng Yang served Liu Zhang in a minor capacity before being punished; after Liu Bei entered Shu he attached himself to Liu Bei via Pang Tong and Fa Zheng and was promoted to治中從事. His relationship with Zhuge Liang was tense: Zhuge Liang treated him with surface courtesy but did not trust him and advised Liu Bei to sideline him. His fate was sealed when Ma Chao, fearing his own position, reported his words to Liu Bei.
Qin Mi
Peng Yang was one of the few people he respected; he recommended Qin Mi to the Administrator Xu Jing in a flowery letter comparing him to ancient worthies.
Anecdotes and allusions
Lying on Pang Tong’s couch
When Peng Yang first went to see Pang Tong, he had no prior acquaintance and Pang Tong had guests. Peng Yang went straight to Pang Tong’s bed, lay down, and said he would have a proper talk when the guests left. After they left he had Pang Tong eat with him first, then talked at length and stayed overnight. Pang Tong was very impressed and, with Fa Zheng, recommended him to Liu Bei.

“Old soldier” and “you outside, I inside”
After his appointment as Administrator of Jiangyang, Peng Yang complained to Ma Chao and called Liu Bei “that old soldier” and said “you take the outside, I’ll take the inside; the realm is not hard to settle.” Ma Chao reported this; Peng Yang was arrested and executed despite his prison letter to Zhuge Liang explaining that he had meant only loyalty.

Romance of the Three Kingdoms
In the novel, Peng Yang’s courtesy name is given as Yongyan (永言). He appears during the conquest of Yi Province and warns about enemy plans to release floodwaters, leading to the capture of Leng Bao. Later, when Liu Bei moves against Meng Da, Peng Yang is portrayed as sending a letter to Meng Da; the letter is intercepted by Ma Chao, who then draws him out over drink. Peng Yang drunkenly speaks treason; he is imprisoned and executed. The historical record does not mention any link between Peng Yang and Meng Da.
Achievements
Peng Yang’s documented achievements include:
- Being recommended by Pang Tong and Fa Zheng and serving Liu Bei effectively in conveying military orders during the takeover of Yi Province
- Promotion to Chief Clerk for the Army (治中從事)
- Recommending Qin Mi to Xu Jing in a letter that became well known
Behind the scenes
Historical sources
Peng Yang is recorded in the Records of the Three Kingdoms (三国志) by Chen Shou, in the “Biographies of Liu Feng, Peng Yang, Liao Li, Li Yan, Liu Yan, Wei Yan, and Yang Yi” (劉彭廖李劉魏楊傳) in the Shu section. The Huayang guo zhi (華陽國志) states that Zhuge Liang advised Liu Bei to have Peng Yang executed for his conduct.
Historical vs literary portrayal
The Romance of the Three Kingdoms changes his courtesy name to Yongyan, gives him a role in foiling the flood scheme and a connection to Meng Da, and has his treasonous talk occur when drunk in front of Ma Chao. The novel preserves the theme of arrogance and fatal speech.
Chen Shou’s evaluation
Chen Shou groups Peng Yang with Liao Li as men “advanced for their talent” whose “actions and norms … brought disaster and blame, all of their own making.”
Historical evaluations
Contemporary
Zhuge Liang: “Peng Yang’s heart is broad and his aims wide; he is hard to keep safe.”
Ma Chao (to Peng Yang): “Your ability is outstanding and the lord treats you with great weight, saying you should rank with Kongming and Xiaozhi—how could he send you to a small commandery and disappoint expectations?”
Chen Shou
Chen Shou: “Peng Yang and Liao Li were advanced for their talent … Look at their actions and norms; the disasters and blame they brought were all of their own making.”
Legacy
Peng Yang is remembered as a talented but overbearing official whose pride and careless words to Ma Chao led to his execution. His prison letter to Zhuge Liang is often cited to illustrate both his rhetorical skill and the irreversibility of his fate once his words were reported.
