Chen Xun 陈勋 — Disciple of Xu Xun and Keeper of the Yulong Palace

Chen Xun (陈勋) — the Sichuan-born Taoist who journeyed from Qingcheng Mountain to Xu Xun's Yulong Palace community, where he served as keeper of the classics and guardian of the medicine furnace until his ascension in 374 CE.

Historical Context: The Jingming Dao and Its Twelve Perfected

Chen Xun (陈勋) was a native of Shu (蜀, present-day Sichuan Province). The Jingming Dao (净明忠孝道, Pure Brightness Loyal and Filial Way) is the Jiangxi Taoist tradition centered on the cult of Xu Xun (许逊, 239–374 CE), the Perfected Lord of Jade Beneficence (玉隆大帝). The tradition venerates a group of Twelve Perfected (十二真君) — the core disciples who surrounded Xu Xun during his lifetime and ascended with him in 374 CE. Chen Xun is one of these Twelve Perfected, making him a founding figure of one of the most important regional Taoist traditions in Chinese history.

Qingcheng Mountain: First Cultivation Under Gu Yuanzi

Chen Xun first entered Qingcheng Mountain (青城山) in Sichuan to study under Gu Yuanzi (顾元子), seeking the method of transcending the mortal realm. Qingcheng Mountain is one of the most important Taoist sacred sites in China — it was on Qingcheng Mountain that Zhang Daoling (张道陵) is said to have received the revelation that founded the Celestial Masters tradition in 142 CE, and the mountain has been a center of Taoist practice continuously since the Han dynasty. Chen Xun's study under Gu Yuanzi on Qingcheng Mountain places him within this ancient Sichuan Taoist tradition before his journey east to join Xu Xun's community.

Joining Xu Xun: From Qingcheng to Yulong Palace

Upon hearing of the deeds of Xu Xun (许逊), the Perfected Lord of Jingyang (旌阳真君) — then serving as the magistrate of Jingyang County (旌阳令) in Sichuan before his later association with Yuzhang — Chen Xun traveled to pay a visit and entered his service as a scribe (作小吏). He became a formal disciple of Xu Xun and was assigned two of the most important custodial roles in the community:

• Managing the Classics and Records (掌典籍): responsibility for the community's library of Taoist texts — the scriptures, ritual manuals, and transmission documents that formed the intellectual and ritual foundation of Xu Xun's practice
• Tending the Medicine Furnace (守药炉): responsibility for the alchemical furnace in which Xu Xun's elixirs were prepared — a role requiring both technical knowledge and the ritual purity necessary to maintain the sacred space of the laboratory

Yulong Palace and Chengxian Mansion

Chen Xun resided in the west corridor of Yulong Palace (玉隆宬西廊), in a residence called Chengxian Mansion (承仙馆), also known as Xiaoju Taoist Abbey (小举道院) — named after his courtesy name. Yulong Palace was Xu Xun's principal sacred site in Yuzhang (豫章, present-day Nanchang, Jiangxi), which would later develop into the Yulong Wanshou Palace (玉隆万寿宬) — the most important Jingming Dao sacred site and one of the major Taoist temple complexes of Jiangxi Province.

Collective Ascension in 374 CE

Chen Xun passed away in the second year of the Ningkang era (宁康二年, 374 CE) — the same year as both Xu Xun and Wu Meng (吴猛). The simultaneous ascension of the teacher and multiple disciples in the same year is one of the most distinctive features of the Jingming Dao hagiographical tradition, understood as a collective liberation in which the entire community of practitioners ascended together. This collective ascension narrative reinforces the Jingming Dao's emphasis on community and mutual cultivation as the path to immortality.

In the second year of the Zhenghe era (政和二年, 1112 CE), Song Emperor Huizong posthumously granted Chen Xun the title Zhengte Zhenren (正德真人, True Person of Rectitude and Excellence) — part of his systematic program of honoring Taoist figures with imperial titles.

Zhengyi Perspective

In the Zhengyi tradition, Chen Xun's role as keeper of the classics and guardian of the medicine furnace reflects the understanding that the transmission of Taoist knowledge requires not only inspired masters but also dedicated custodians — practitioners whose vocation is to preserve, protect, and transmit the texts and ritual materials that make the tradition's continuity possible. The Zhengyi tradition's own system of talisman register transmission depends on precisely this kind of custodial care: the registers must be properly stored, the transmission documents correctly maintained, and the ritual materials prepared with the appropriate purity and attention.

Chen Xun's journey from Qingcheng Mountain in Sichuan to Xu Xun's community in Jiangxi also reflects the geographic mobility of the early Taoist practitioner — the willingness to travel great distances in search of the right teacher and the right community. This pattern of seeking — studying under one master, then traveling to find a more advanced teacher — is the same pattern that the Zhengyi tradition's own transmission history embodies: each generation of Celestial Masters has sought to deepen and extend the tradition received from the previous generation, traveling, studying, and transmitting across the vast geography of Chinese Taoism.
