Did Zhuge Liang Know Qi Men Dun Jia? The Eight Formations, Borrowing the East Wind and the Empty Fort: What Is Historical

Zhuge Liang is probably the name most often attached to Qi Men Dun Jia: some say he borrowed the east wind with it, others say the Eight Formations are a Qi Men formation. There is only one way to judge: go back to the earliest source and see which book each story is in. This is a history and sources article; it makes no judgement about any particular date.

Three layers first

• Found in the official histories: things in the Sanguozhi biography and Pei Songzhi’s commentary.
• An early source, but read with a discount: found in commentary quotations or Jin-era notes, with details reworked later.
• Fiction or legend: from Romance of the Three Kingdoms, or oral tradition with no contemporary record.

One table

Event	Earliest source found	How to read it
Longzhong plan, three visits to the cottage	Sanguozhi, “Zhuge Liang”; his own words in the Memorial on Leading the Army	History. A strategic analysis of politics and geography, not divination
Made the Eight Formations	Sanguozhi, “Zhuge Liang”: “worked out military method and made the Eight Formations”	A documented formation treatise; details of the stone formation are half history, half legend
Wooden ox and flowing horse	Sanguozhi biography; Pei’s commentary quoting the Zhuge Liang Ji	History: transport for the northern campaigns; the real structure is still unsettled; “walks by itself” is embellishment
Improved repeating crossbow (Yuanrong)	Pei’s commentary quoting Wei Shi Chunqiu	An improvement, not an invention; the “ten bolts from one crossbow” record can be checked
Seven captures of Meng Huo	Xi Zuochi’s Han Jin Chunqiu (quoted by Pei), Huayang Guozhi	Has a source but a brief one; seven different tactics are the novel’s addition
Empty Fort Strategy	Guo Chong’s Tiao Liang Wu Shi (Jin dynasty), quoted and rejected by Pei Songzhi	An early version exists but Pei refuted it; the novel moves it to Xicheng after Jieting
Straw boats borrow arrows	Romance of the Three Kingdoms, chapter 46	Fiction. The histories have a different prototype with a different person: Sun Quan’s boat taking arrows (Pei, quoting the Weilüe)
Borrowing the east wind, Seven-Star Altar	Romance of the Three Kingdoms, chapter 49	Fiction. In the histories the Red Cliffs fire attack is Zhou Yu’s and Huang Gai’s plan
Eight Formations trap Lu Xun	Romance of the Three Kingdoms, chapter 84	Fiction
Seven-star lamps to prolong life	Romance of the Three Kingdoms, chapter 103	Fiction. The histories record only that he died at Wuzhang Plains
Rain at Shangfang Valley, summoning the Six Ding and Six Jia	Romance of the Three Kingdoms, chapter 103 and others	Fiction. The Six Ding and Six Jia are names in the Daoist pantheon
Kongming lanterns, mantou from the offering to the Lu River	Folk legend (the mantou story already appears in the Song Shiwu Jiyuan)	Legend with no contemporary record
Ma Qian Ke, Zhuge Shen Shu	Prophecy books from the Ming and Qing	Falsely attributed; no connection to Zhuge Liang’s works recorded in the Sanguozhi

Three of the most asked

The Eight Formations. “Made the Eight Formations” is stated in the histories; it is a set of formations. Legend then turned it into a stone formation at Yufu Pu in Kuizhou: stones set along the eight-trigram directions, divided into the doors Rest, Life, Harm, Block, Scenery, Death, Fright and Open, said to be able to trap a hundred thousand men. Du Fu’s poem says “the river flows but the stones do not move”, and Song sources mention stone formations, in more than one place. But “the stones move by themselves, trap Lu Xun, and only Huang Chengyan can lead him out” is how chapter 84 of the novel tells it; in the histories Lu Xun withdrew for military reasons.

The Empty Fort. Its source can actually be found: Guo Chong of the Jin dynasty lists it as Zhuge Liang’s third deed in the Tiao Liang Wu Shi, saying that as Sima Yi’s army approached Zhuge Liang opened the gates and lowered the banners, and Sima Yi suspected an ambush and withdrew. But Pei Songzhi, writing his commentary, rejected Guo Chong point by point, because at the time Sima Yi was garrisoned at Wancheng and was not there at all. The novel took Guo Chong’s account and moved the place to Xicheng after Jieting. A similar “open the gates and the enemy retreats” story has a different protagonist in the histories: the Nan Qi Shu records Xiao Chengzhi holding Shouchun, also opening the gates, with the enemy suspecting an ambush and leaving.

Borrowing the east wind and the straw boats. Both are famous scenes of the novel. In the east-wind scene the novel itself, through Lu Su, says Zhuge Liang simply “knew the season”; the altar was for Zhou Yu’s benefit. The historical Red Cliffs was a fire attack by Zhou Yu and Huang Gai, and the wind shift was a winter climate effect on the Yangtze. The prototype of the straw boats is a story in Pei’s commentary quoting the Weilüe: Sun Quan sailed a large ship to observe Cao Cao’s army, arrows struck one side, and he turned the ship so the other side took arrows to level it; a different person and a different occasion.

Then why do people say Zhuge Liang knew Qi Men

There are two reasons. First, Qi Men books like to list a lineage of heirs: Yellow Emperor, Feng Hou, Jiang Taigong, Huang Shigong, Zhang Liang, Zhuge Liang, Liu Bowen. This is a later “founders’ story”; the people in it are mostly real, but “X personally passed Qi Men to Y” has no contemporary record. Second, the legend of the Eight Formations has the names Rest, Life, Harm, Block, Scenery, Death, Fright and Open, exactly the Eight Doors of Qi Men, so the two got merged. But a formation is how soldiers stand on a battlefield, and a Qi Men chart is a diagram cast by time; they are different things. For the meaning of the Eight Doors, see the Eight Doors explained.

What Zhuge Liang really left is more solid than the legends: a far-sighted strategy, an improved crossbow, a wooden ox built to carry grain, and a southern settlement of “no garrison and no grain convoy”. In the Tang Taizong Li Weigong Wendui, a text included in the Seven Military Classics in the Song (generally thought to be written by later hands in their names), Li Jing is made to remark that the seven captures were “just orthodox troops”, a line often quoted against the supernatural account.

How to read it

1. The people and events in the official histories are broadly reliable, but the histories do not say they won by Qi Men.
2. Do not take fiction as historical conclusions; and even for a legend with an early source, check whether people at the time already rejected it (as with the Empty Fort).
3. For a book attributed to an ancient figure, ask about its edition and date first.

Our position

Qimena does not borrow the fame of historical figures and does not treat any legend as proof that Qi Men works. We cast charts by published rules and give readings: the rules and their verification are in how Qimena casts a chart; for the written record on where Qi Men comes from, see the origin of Qi Men Dun Jia.
