The Trials of Tang Gongfang 唐公房的考验

李八百，蜀人也，莫知其名。历世见之，时人计之，已年八百，因以号之。知汉中唐公房有志学道，乃化为病者诣之。公房迎之，八百使公房为己舐恶疮。公房即为舐之。八百曰："疮愈，当以三十斤美酒相劳。"公房即具酒。如此数年，不倦。八百乃使公房夫妻及三婢舐之。又使舐牛马。公房一一为之。

Translation

Li Babai was a man of Shu. No one knew his real name. He had been seen across multiple generations, and people calculated that he was already eight hundred years old — hence his nickname, "Li Eight-Hundred."

He learned that a man named Tang Gongfang in Hanzhong had set his heart on studying the Dao. Li Babai disguised himself as a diseased beggar and went to Tang Gongfang's door. Tang Gongfang welcomed him warmly. Li Babai said: "I have foul sores on my body. Will you lick them clean for me?" Tang Gongfang did so without hesitation.

"When my sores heal," Li Babai said, "you must reward me with thirty jin of fine wine." Tang Gongfang provided the wine. This went on for years. Tang Gongfang never complained.

Then Li Babai escalated: he demanded that Tang Gongfang's wife and three servant girls also lick his sores. Then he demanded that they lick the sores of his oxen and horses. Tang Gongfang did everything — without disgust, without refusal.

The Revelation 真相大白

八百乃以丹经授公房，公房入云台山中作药。药成，服之仙去。

Only then did Li Babai reveal himself. He was not a beggar, not a leper — he was an immortal who had lived eight centuries. Every humiliation was a test. Tang Gongfang's willingness to serve the most disgusting, degrading needs of a stranger proved that his heart was truly selfless. Li Babai gave him the scriptures of alchemy. Tang Gongfang entered Mount Yuntai, prepared the elixir, took it, and ascended to heaven as an immortal.

🧪 The Alchemy of Character In Ge Hong's Daoist framework, the elixir of immortality is not merely a chemical substance — it requires the practitioner to be worthy of consuming it. The external elixir (外丹, waidan) of cinnabar and mercury is meaningless without the internal elixir (内丹, neidan) of moral purification. Li Babai's tests are designed to forge the internal elixir. Tang Gongfang must prove that he can endure disgust, servitude, and degradation without losing his compassion. Only then is the outer elixir safe to give him.

Analysis 解读

The tests are deliberately escalating in their unpleasantness. Licking a stranger's sores is bad enough. Making one's wife and servants do the same is worse. Making them lick animal sores is the ultimate degradation. Each level tests a different dimension of character: personal humility, authority over others, and the willingness to treat all beings — human and animal — with equal compassion.

The story also reveals something about the Daoist view of the body. In Confucian culture, the body is sacred — "身体发肤，受之父母" (body, hair, and skin are received from one's parents). Li Babai's demand that Tang Gongfang defile his body is therefore not just unpleasant but culturally transgressive. The test is designed to break the disciple's attachment to social propriety, to make him realize that the Dao transcends human conventions of cleanliness and dignity.

📖 Cross-Cultural Parallel: Job and the Bodhisattva Li Babai's testing of Tang Gongfang has parallels in multiple traditions. The biblical Book of Job presents a righteous man tested by God through suffering. In Buddhist literature, the Bodhisattva is tested through self-sacrifice — giving away his body to feed a starving tigress, for example. The Chinese version is distinctive in its emphasis on service rather than suffering. Tang Gongfang does not endure pain; he endures humiliation. His virtue is not patience but compassion.
