Zhang Yun 张氲 — The Hermit Who Refused the Tang Court
Paul PengEmperor Xuanzong summoned Zhang Yun (张氲) to the Zhanlu Hall in 719. Zhang answered the emperor's questions. The emperor was satisfied. He offered Zhang the position of Taichangqing — Minister of Rites, one of the most prestigious posts in the Tang government. Then, when Zhang declined that, he offered him Situ — one of the Three Excellencies, the highest tier of civil office in the empire.
Zhang declined that too. He asked to go back to his mountain. The emperor let him go.
This was the second time Zhang Yun had refused a court appointment. The first had been under Empress Wu Zetian, nearly twenty years earlier. He was consistent about it.
Key Takeaways
- Zhang Yun 张氲 (653–745, styled Cangzhen, self-titled Hongyazi 鸿涯子) was a native of Shenshan in Jinzhou (晋州, now part of Shanxi Province) during the Tang Dynasty
- From youth he was devoted to the doctrines of Huangdi and Laozi; he traveled to Mount Qinggai and studied under the master Jing Chengzi
- He spent fifteen years in seclusion on Mount Guye, mastering esoteric Daoist scriptures
- During the Shengli era (698–700) of Empress Wu Zetian, he was summoned to court but declined the official post; he then resided at the home of the court official Li Qiao in Luoyang for thirteen years, during which "people competed to associate with him"
- In 719 CE (Kaiyuan 7), Emperor Xuanzong summoned him to the Zhanlu Hall; his answers satisfied the imperial will, and he was offered Taichangqing (Minister of Rites) and then Situ (one of the Three Excellencies) — he declined both
- He returned to his mountain and practiced jueli fuqi (绝粒服气, bigu and breath cultivation), never going out again
- He wrote ten volumes of Biographies of Virtuous Hermits, twenty volumes of Records of Immortals, thirty volumes of Records of Hedong, and ten volumes of Great Zhou's Profound Words — none published in his lifetime
- He also annotated the Laozi (Tao Te Ching), the I Ching, the Three Rituals, and the Guliang Zhuan; three of his poems survive

Zhang Yun (张氲, 653–745), styled Hongyazi — Tang Dynasty Daoist hermit who twice refused imperial appointment, spent fifteen years on Mount Guye, and returned to his mountain after satisfying Emperor Xuanzong's questions to practice bigu until his death at ninety-three.
Note on the title "Hongyazi" (鸿涯子): The hongya (鸿涯) evokes the image of a great bird at the edge of the vast sky — a classical Chinese metaphor for the recluse who lives beyond the reach of worldly entanglement. Zhang Yun's self-assumed title was not a casual choice. It was a statement about how he understood his own vocation.
Fifteen Years on Mount Guye
Before the imperial summons, before the years in Luoyang, before the audience with Emperor Xuanzong — there were fifteen years on Mount Guye. Zhang Yun went there after studying under Jing Chengzi on Mount Qinggai, and he stayed for fifteen years, mastering esoteric Daoist scriptures and books.
Fifteen years is a long time to spend on a mountain. It is long enough to read everything, to practice everything, to understand not just the content of the tradition but its texture — the way the different scriptural currents relate to each other, the way practice changes over years rather than months, the way solitude works on a person who takes it seriously. By the time Zhang Yun came down from Mount Guye, he had been shaped by the mountain in ways that no amount of court life could undo.
The Luoyang Years: Thirteen Years at Li Qiao's Home
After declining Empress Wu Zetian's summons, Zhang Yun did not return immediately to the mountains. He spent thirteen years at the home of Li Qiao — a Ji shizhong, one of the highest-ranking officials at the Wu Zetian court — in Luoyang. The sources say that during this period, "people competed to associate with him."
This is an interesting detail. Zhang Yun had declined official position, but he had not declined society. He was living in the home of a senior court official, in the Tang capital, surrounded by people who wanted to know him. The Daoist hermit who refuses office but remains accessible — who declines the formal role but continues to engage with the world on his own terms — is a recognizable figure in the Tang biographical tradition. Zhang Yun inhabited that role for thirteen years in Luoyang before eventually returning to his mountain practice.
The Audience with Emperor Xuanzong
In 719, Emperor Xuanzong — the most Daoist-identified emperor of the Tang, the man who would go on to personally annotate the Dao De Jing and compile the Kaiyuan Daozang — summoned Zhang Yun to the Zhanlu Hall. Zhang answered his questions. The emperor was satisfied enough to offer him the Ministry of Rites. When Zhang declined, the emperor offered him Situ — one of the Three Excellencies, the highest tier of civil office in the empire.
Zhang declined that too, and asked to return to his mountain. What followed was the final phase of Zhang Yun's life: jueli fuqi (绝粒服气), never going out again, writing works that he never published.
The Unpublished Works
Zhang Yun wrote prolifically and published nothing. Ten volumes of Biographies of Virtuous Hermits. Twenty volumes of Records of Immortals. Thirty volumes of Records of Hedong. Ten volumes of Great Zhou's Profound Words. Annotations on the Laozi, the I Ching, the Three Rituals, and the Guliang Zhuan. Three poems that survived.
The decision not to publish is itself a statement. A man who had twice refused the highest offices in the empire was not going to seek literary fame. The works existed because he wrote them — because the act of writing was part of his practice, his way of working through what he understood. Whether anyone else read them was a separate question, and apparently not one he found pressing.
What This Kind of Life Looks Like from the Inside
The Daoist tradition has always had a complicated relationship with political power. The Zhengyi (正一) tradition, rooted at Longhu Mountain (龙虎山), has historically engaged with imperial courts — performing rituals, advising rulers, accepting titles and patronage. But it has also always produced figures like Zhang Yun: practitioners who engage with the court on their own terms, answer the emperor's questions honestly, and then go back to the mountain.
The refusal of office is not a rejection of the world. It is a statement about what kind of engagement with the world is compatible with genuine cultivation. Zhang Yun spent thirteen years in Luoyang, in the home of a senior official, surrounded by people who wanted to know him. He was not hiding. He was choosing the terms of his engagement — and those terms did not include formal office.
If you find yourself drawn to the question of how the Daoist tradition navigates the relationship between cultivation and worldly engagement — between the mountain and the court, between practice and responsibility — Zhang Yun's life is one of the most instructive examples in the Tang biographical record.
