Cao Gujiu 曹谷就 — The Imperial Kinsman Who Chose the Mountains
Paul PengHis original name was Cao Jingxiu (曹景休). He had imperial connections — the Northern Song court was not far from him by birth. He had no interest in it. By nature quiet and tranquil, he wanted no part of official life. So he changed his name — to Cao Gujiu (曹谷就), a name that expressed his intention to settle in the cliffs and valleys and cultivate his nature there.
Then, according to the sources, he met Zhongli Quan (钟离权) and Lü Dongbin (吕洞宾). They taught him the secret essentials of the Huanzhen Golden Elixir (还真金丹). Before long, he attained the Dao.

The Name Change: What Cao Gujiu Means
The name change from Cao Jingxiu (曹景休) to Cao Gujiu (曹谷就) was not incidental. In the Chinese tradition, a name change of this kind is a declaration — a public statement of intention and identity. The new name, Gujiu (谷就), carries the meaning of "dwelling in the valley" or "settling in the valley" — an image drawn from the Daoist tradition of the valley as a place of receptivity, humility, and cultivation.
The Dao De Jing uses the valley as a recurring image: "The spirit of the valley never dies" (gu shen bu si 谷神不死); "Know the masculine, keep to the feminine, and be the valley of the world" (wei tianxia gu 为天下谷). To name oneself "valley-dweller" was to align oneself with this Daoist imagery — to declare that one's practice was oriented toward receptivity and return rather than toward assertion and advancement. His literary name, Hunchengzi (混成子, "Child of the Undifferentiated Whole"), reinforces this: huncheng (混成) refers to the primordial, undifferentiated state from which all things arise, described in the Dao De Jing as the nature of the Dao itself.
Zhongli Quan, Lü Dongbin, and the Zhong-Lü Transmission
The two immortals Cao Gujiu claimed to have met — Zhongli Quan (钟离权) and Lü Dongbin (吕洞宾) — are among the most important figures in the Daoist inner alchemy tradition. Zhongli Quan is understood as the patriarch of the Zhong-Lü lineage of inner alchemy; Lü Dongbin is his most famous disciple and the figure through whom the tradition was most widely transmitted. Together, they represent the foundational transmission of the inner alchemy methods that would become central to the Quanzhen (全真) school of Daoism.
The teaching they transmitted to Cao Gujiu — the "secret essentials of the Huanzhen Golden Elixir" (还真金丹秘要) — belongs to this inner alchemy tradition. Huanzhen (还真, "returning to the true") describes the goal of inner alchemy practice: the refinement of the practitioner's vital substances until they return to their original, undifferentiated state — the state of the Dao before differentiation. The Golden Elixir (jindан 金丹) is the inner alchemy's central metaphor for this refined state.
Cao Gujiu and Cao Guojiu: The Historical and the Legendary
The figure of Cao Gujiu in this biography overlaps significantly with the legendary figure of Cao Guojiu (曹国舅) — one of the Eight Immortals (八仙) of the Daoist tradition. Cao Guojiu is traditionally identified as a relative of Empress Cao of the Northern Song, who abandoned his imperial connections to pursue Daoist cultivation and was eventually initiated by Zhongli Quan and Lü Dongbin. The parallels with Cao Gujiu's biography are clear: the imperial connections, the rejection of official life, the encounter with the same two immortals, the attainment of the Dao.
Whether Cao Gujiu and Cao Guojiu are the same historical person recorded under different names, or whether the legendary figure of Cao Guojiu absorbed elements from the biography of a historical practitioner named Cao Gujiu, the sources do not resolve. What they preserve is a consistent pattern: a person of imperial background who chose the mountains over the court, and who received the inner alchemy transmission from the tradition's most celebrated masters.
Why Cao Gujiu Still Matters
Cao Gujiu had access to the imperial world and chose not to use it. He changed his name to say so. The Zhengyi (正一) tradition understands that the Dao is not served by rank or connection — that the person who walks away from privilege to cultivate in the valleys is making a choice that the tradition recognizes and honors. The meeting with Zhongli Quan and Lü Dongbin — whether understood as a literal encounter with immortals or as an encounter with the living transmission of the inner alchemy tradition — produced a practitioner who attained the Dao. That is the record. The name he chose for himself — valley-dweller, child of the undifferentiated whole — describes both the practice and the result. If you want to understand what the Golden Elixir tradition is and why it matters, Cao Gujiu's story is one place to begin.
