Mingde Pharmacy was hidden between a bicycle shop and a phone repair store, as if the city had built the present around it and then forgotten to push it out. Lin Xuan arrived there at dusk with the address written on a napkin by Doctor Sun. He was not looking for a miracle cure for Gu Qingxue. He distrusted solutions sold with too much confidence. He was looking for language. There were parts of the body modern medicine described with impeccable numbers, and others old doctors named with metaphors born from centuries of watching wrists, eyes, and tongues beneath yellow lamps.
Inside, the air was thick with the smell of dried roots, citrus peel, old wood, and medicinal dust. Behind the counter, a white-bearded man weighed herbs on an arm balance as though measuring time rather than grams. Doctor Sun had not called him master, but he had spoken of him with a respect Lin Xuan rarely heard him use. 'You must be the young man who asks uncomfortable questions,' the old man said without lifting his head. Lin Xuan bowed slightly. 'That depends on who hears them.'
The man's name was He Shou'an, and he had once practiced traditional medicine in a rural hospital before retiring. He did not appear impressed by the white coat Lin Xuan was not wearing or the titles he did not mention. He asked him to describe the case without names or wealth. Lin Xuan obeyed. He spoke of episodes of peripheral coldness, migrating chest pain, exhaustion afterward, sensitivity to stress, and strange responses to certain medications. He Shou'an listened with his eyes half closed. Now and then he picked up a root, smelled it, and returned it to its drawer.
When Lin Xuan finished, the old man did not give a diagnosis. He said, 'Some bodies do not break like a vessel. They close like a besieged city. From outside you see walls. Inside, circulation is lacking, messages are missing, calm is gone.' Lin Xuan did not write the sentence down immediately. He let it enter. 'Are you talking about stasis?' 'I am talking about not locking an entire life inside one word. You modern young doctors love labels. Bad old doctors love proverbs. Both can be useless.'
The old man asked for his wrist. Lin Xuan was surprised. 'I am not the patient.' 'Any doctor who wants to read a pulse should first know how his own sounds when he lies and says he is not tired.' The observation was too direct for an elegant defense. Lin Xuan extended his hand. He Shou'an placed three fingers over his pulse and closed his eyes. Nearly a minute passed. 'Too much fire above, too little root below,' he declared. 'That is not very scientific.' 'Neither is fainting from working as if your body were borrowed.'
He Shou'an then spoke of patterns that did not pretend to replace examinations, but to guide questions: cold preceding pain, a pulse becoming thin from vascular withdrawal, exhaustion that might mean an internal war rather than simple weakness. Lin Xuan translated each idea mentally into terms he could defend before a committee: autonomic tone, microcirculation, low-grade inflammation, endothelial response. Not everything fit. Some things sounded like dangerous poetry. Others lit small lamps over Gu Qingxue's map.
Before leaving, Lin Xuan bought a brown-covered notebook sold beside packets of dried ginger. He Shou'an wrote four characters on the first page with a brush: see before touching. 'Shouldn't it be cure before charging?' Lin Xuan asked. 'That is assumed. It does not deserve ink.' Outside, Yunhe's sky was violet and electrical wires cut the light into crooked lines. Lin Xuan walked with the notebook under his arm, feeling he had received something uncomfortable: not a technique, but an obligation to be more precise in his humility.
The next day, he presented the new observations to Doctor Sun. The old physician read the plan slowly, then raised his eyes. 'You went to see He.' 'You sent me.' 'I gave you an address. I did not send you to believe him.' Lin Xuan understood the difference and nodded. Sun placed the paper on the desk. 'This may be useful. Not because it sounds ancient and not because it sounds modern. Because it forces observation during the episode, not after everyone cleans the blood and writes something pretty.'
He kept the brown notebook beside his surgical notes, not apart from them. That felt important. The medicine he sought could not be divided into comfortable compartments: modern here, ancient there; clean ward here, dusty pharmacy there. The human body respected none of those borders. It bled, trembled, compensated, remembered, defended itself. A doctor who wanted to master it had to accept that every certainty was only a tool, not a throne.
The brown notebook became an uncomfortable presence in his pocket. Every time he touched it, he remembered He Shou'an's dry fingers on his wrist and the sentence about the borrowed body. Lin Xuan did not want to romanticize the old herbalist. He knew many ancient words could become smoke if no one forced them to touch data. But he also knew modern doctors had their own superstition: believing that what did not appear clearly on a screen did not deserve patience. Between both errors he had to cut a path.
That afternoon he tested the new record on an ordinary patient before applying it to Qingxue. It was a man with vague dizziness and poorly hidden anxiety. Lin Xuan looked for no rare disease; he only observed hand temperature, postural changes, and the relation between breathing and pulse. The case turned out simple, almost banal, but it helped him adjust the method. Not every lesson needed a mysterious patient or a reserved room. Sometimes technique was sharpened with ordinary lives, with people no one outside their family would remember.
When he spoke again with Doctor Sun, the old physician showed him a yellowed file from twenty years earlier. It was a lost case, a woman with strange episodes who never received a clear diagnosis. 'I am not showing you this so you can find the answer now,' Sun said. 'I am showing you so you understand unresolved cases do not disappear. They remain inside doctors like small debts.' Lin Xuan ran his fingers along the paper's edge. Suddenly, Gu Qingxue's illness did not seem like an isolated challenge, but part of a long line of voices medicine had left unfinished.
When he left the office, the hospital seemed different. Every door might hide a case someone had simplified out of fatigue. Every diagnosis written with confidence might have a crack. The thought did not make him paranoid; it made him slower, more attentive. In the elevator, an intern asked why he carried an old notebook beside an anatomy atlas. Lin Xuan answered without thinking too much: 'So I do not forget that looking is also a technique.' The intern did not understand. Perhaps one day he would.
The old herbalist did not let Lin Xuan leave immediately. He closed the shop for a few minutes and invited him to sit behind the counter, where a teapot blackened by years of use waited on a narrow shelf. The tea was bitter and weak, but the old man served it with a solemnity that did not allow refusal. "Young doctors want quick answers," he said, watching the steam. "The rich want expensive answers. The sick want answers that do not make them feel alone. If you confuse those three things, you will do harm even when you are correct." Lin Xuan held the warm cup between his hands. He thought of Qingxue, of her records, of the specialists who had charged enormous fees for incomplete names.
On one wall of the shop hung an old portrait of a rural physician. The ink had faded, but the eyes were still alive. The herbalist explained that he had been his teacher, a man who lost his reputation because he refused to prescribe useless tonics to powerful families. "He died poor," the old man said, "but peasants from three villages walked through rain to bury him. That is a kind of wealth that never appears in ledgers." Lin Xuan listened in silence. The system could give him Merit Funds, grants, and legal rewards, but the sentence reminded him that clean money was not enough. The reason for accepting it also had to remain clean.
Before leaving, he bought a small yellowed notebook in which the old man wrote traditional mixtures for restoring strength after long illness. Lin Xuan did not intend to use it as a miraculous formula. He bought it because the margins contained notes about patience, appetite, fear, and family. It was medicine written by someone who had seen patients in their kitchens, not only beneath white lights. On his way back to the hospital, Lin Xuan placed the notebook beside Qingxue's file. Perhaps none of those observations would cure her rare condition, but they could remind him of something the operating room easily forgot: a body was not only anatomy. It was memory too.
