The Gu Huan 顾欢

Gu Huan, who lived during the Song and Qi dynasties of the Southern Dynasties, was a native of Yanguan in Wujun Commandery (now Haining City, Zhejiang Province, China). His courtesy names were Jingyi and Xuanping.

In his early years, his family was poor, and he made a living by farming.

He had a keen interest in Confucianism and was fond of the teachings of Huangdi (the Yellow Emperor) and Laozi (founder of Taoism). At the age of twenty, he studied under Lei Cizong, delving into the philosophical principles of Xuanxue (Neo-Taoism) centered on the works of Laozi and Zhuangzi, and became proficient in books on Yin-Yang (the ancient Chinese concept of opposing yet complementary forces).

He was well-versed in Taoist doctrines and numerological arts, and his practices often yielded effective results.

After his mother passed away, he chose to live in seclusion and refused to take up official positions. He retreated to Tiantai Mountain in Shanyin County to cultivate the Taoist art of self-cultivation (focused on physical and spiritual refinement). He established a school to teach disciples, composed works to expound his theories, and attracted a large number of followers. Xiao Daocheng, Emperor Gao of the Qi Dynasty, admired his moral teachings and summoned him to serve as the Chief Secretary of Yangzhou (a key local administrative position). Gu Huan complied with the imperial edict and went to the capital, presenting his works such as Zheng Gang (Outline of Governance) and Laozi Daode Jing Yishu (Commentary on the Meaning of Laozi’s Tao Te Ching). However, he later resigned from his post and returned to his hometown.

In the first year of the Yongming era of Emperor Wu of the Qi Dynasty (483 AD), he was summoned again to serve as a Doctor of the Imperial Academy (a senior academic official responsible for teaching and scholarly research), but he declined once more. In his later years, he focused on taking Taoist elixirs (a practice aimed at longevity and spiritual transcendence) and avoided social interactions with others. He eventually passed away on Shanyi Mountain (now Shengzhou City, Zhejiang Province). Emperor Wu of the Qi Dynasty, Xiao Ze, issued an imperial edict ordering Gu Huan’s sons to collect his posthumous works and compile them into a 30-volume book titled Wenyi (Collected Essays and Discourses).

Gu Huan authored Zhenji Jing (Scripture of Authentic Handwritings), in which he organized the authentic handwritten Taoist scriptures by Yang Xi, Xu Mi, and Xu Hui—key figures of the Shangqing School (a major branch of Taoism emphasizing celestial revelations).

His work Yixia Lun (Treatise on the Chinese and the Barbarians) thoroughly debated the similarities, differences, merits, and drawbacks of Taoism and Buddhism. He argued that Taoism was the orthodox teaching of China, while Buddhism was a foreign doctrine from the Western barbarians; yet he also proposed that Taoism and Buddhism shared the same origin but followed different paths, both serving as methods for sages to enlighten all living beings.

He put forward the theory that "Tao is Buddhism, and Buddhism is Tao," while upholding Taoism as the superior one. Due to the fierce tone of the text—advocating "respecting the sovereign and repelling barbarians" (a traditional Chinese ideology emphasizing cultural orthodoxy) and demeaning Buddhism—this immediately triggered a strong counterattack from Buddhists. The dispute between Taoism and Buddhism reached a fever pitch at that time. The debate over "Yixia" (the distinction between Chinese and foreign cultures/religions) became a focal point of arguments between Taoism and Buddhism during the Southern and Northern Dynasties, as well as the Sui and Tang dynasties.
