The auction house catalogue arrived on a Tuesday morning.

Lin Jing Huo placed it on his desk without comment — a thick document, forty-three pages, each lot photographed from multiple angles with accompanying provenance summaries and estimated value ranges. She had already printed a second copy for herself, he noticed, with her own annotation system begun in the margins: yellow for items requiring attention, red for priority items.

He read through it once quickly, establishing the shape of what was there. Then he read it again slowly.

On the third reading he stopped at lot twenty-one.

A blue-white vase. Ming dynasty, Xuande period. Starting bid three hundred thousand yuan. The photographs were taken from four angles — front, back, left side, right side — and one photograph of the base.

He enlarged the photograph of the base on the screen of the flat device Lin Jing Huo had shown him how to use — the laptop, it was called, though it sat on the desk rather than on his lap — and looked at the bottom right corner of the base image.

The resolution was not sufficient to be certain. But the shape of the mark in that corner — the angle, the length, the way it ended — looked familiar in a way that made him sit very still.

'Cao Bao Nian,' he said.

'Yes.'

'The auction next month. Lot twenty-one. Can you tell me anything about the collection it comes from?'

'The Qing dynasty official's collection. I know the general reputation — significant and carefully assembled over three generations. Lot twenty-one would be a major piece from that collection.'

'The photograph of the base. I need to see it at higher resolution.'

'Lin Jing Huo can request that from the auction house. They will usually provide better images to registered serious bidders.'

He called across to Lin Jing Huo's desk: 'Lot twenty-one in the Tianbao catalogue. I need higher resolution photographs of the base. Can we request them?'

She looked up. 'I can contact their specialist today. Do you want to register as a preview attendee as well?'

'Yes. Priority access to lot twenty-one specifically.'

She made a note and returned to what she had been doing, and he returned to the catalogue.

This was the rhythm they had developed in the three weeks since he had left the hospital: he read, assessed, and identified; she organized, communicated, and executed. Not the division of labor between employer and employee that the organizational chart would have described. Something more like the relationship between the person who knew where the good clay was and the person who knew how to move it efficiently from river to workshop.

He had learned the laptop. He had learned the mobile phone — with more difficulty, the interface requiring a fineness of touch with fingertips that his borrowed hands had not yet fully calibrated to. He had learned to use the internet, which remained the most extraordinary thing he had encountered in this era: the accumulated written knowledge of the entire civilization, accessible in seconds, almost entirely unorganized and requiring the same discriminating judgment that distinguished good clay from river silt.

He had spent three days reading everything available about Ming dynasty production workshops before Lin Jing Huo had gently pointed out that he could narrow his search.

'You already know the period,' she had said. 'What specifically are you trying to find?'

'I am trying to understand the practice variations between different workshops within the same period. Whether certain technical approaches were associated with specific production groups.'

She had looked at him with that recalibrating expression.

'There are academic papers on that,' she said. 'I can find the relevant ones.'

She found eleven papers within an hour. He read all eleven. They were useful in places and frustrating in others — useful where they described observable technical characteristics, frustrating where they retreated into attribution debates based on documentation rather than physical evidence.

One paper, by a Professor Chen from Beijing University's art history department, came closest to the question he was actually trying to answer. The paper discussed production practices at the imperial kilns during the Xuande period and included, in a footnote on the third page, a brief mention of glaze application directional conventions.

He read that footnote four times.

'This professor,' he said to Lin Jing Huo. 'Do you know of him?'

'By reputation. He is considered the leading academic authority on Ming dynasty ceramics in China. I have never met him personally.'

'His paper on Xuande production practices cites original workshop records. Does the university make those records available for research consultation?'

She looked at him.

'You want to access the original records.'

'The footnote references a document that would tell me something I need to know. I cannot determine its relevance from the footnote alone.'

She thought for a moment.

'I can make an inquiry through the university library system. It may take time. Academic institutions move slowly.'

'Make the inquiry.'

She made the inquiry. Three days later, she received a response indicating that the records were held in the university's special collections and could be examined by appointment. The waiting list for appointments was six weeks.

'Six weeks is acceptable,' he said.

'I will confirm the appointment.'

Meanwhile, the higher-resolution photographs of lot twenty-one arrived from the auction house. Lin Jing Huo forwarded them to his screen without ceremony, and he opened them and sat for a long time looking at the base image.

The mark was there.

Not definitively — he could not be certain from a photograph, no matter the resolution. The photograph could not give him weight, could not give him the tactile information that the exterior glaze surface would yield under his fingertips. But the shape of the mark, the angle of the terminal stroke, the way it ended not by lifting the tool but by dragging it slightly to the left — these were consistent with what he had seen in the celadon bowl in the warehouse.

The same craftsman. Or his imagination working on insufficient evidence.

He needed to hold the piece.

'The preview,' he said. 'When is it?'

'Friday of next week,' Lin Jing Huo said. 'I have confirmed our registration. We have access to the preview room from two to five in the afternoon.'

'Good.'

He returned to his reading. He had been working through the afternoon's client communications — three inquiries about appraisal services, one from a collector in Shanghai who had heard through a contact that the Gu clan was beginning to operate again — and the work had the texture of reconstruction: slow, requiring attention to each individual component, nothing spectacular but nothing that could be skipped.

Lin Jing Huo was on a call at her desk. He could hear her voice — precise, measured, the voice of someone who never used two words when one would do — relaying information to someone on the other end, answering a question about service terms. He noted without intending to note it that she had changed her explanation of their service offering since two weeks ago: the new version led with methodology rather than with reputation, which was the correct approach given that reputation was currently their weakest asset.

She had changed it without being asked.

He mentioned this during their end-of-day summary.

'The service description you are using with inquiries,' he said. 'It is different from what I heard you say in the first week.'

She looked up from closing her computer.

'The previous framing leaned on the clan's historical reputation as the primary reason to engage us,' she said. 'That framing is currently a liability rather than an asset. I shifted to leading with the examination methodology, which is something we can substantiate regardless of recent history.'

'That was the right call.'

'I thought so.' She closed her bag. 'I should have made it sooner.'

'You made it at the right time. Before that there was not enough demonstrated methodology to lead with.'

She paused in gathering her things. Looked at him.

'You are tracking how I have been framing things to clients,' she said.

'I am tracking everything that affects the recovery. That includes client communication.'

'You did not track it before. You left client communication entirely to me and reviewed only the financial outcomes.'

'That was a mistake I am correcting.'

She was quiet for a moment.

'Most people who delegate and then begin paying closer attention do it because something went wrong with the delegation,' she said carefully. 'Is there something in how I have been handling this that is a concern?'

'No.' He said it directly, because she had asked directly. 'You are handling it well. I am paying attention because I should have been paying attention from the beginning, not because there is a problem.'

She considered this.

'All right,' she said. And then, after a pause: 'Thank you for saying that directly.'

'You asked directly. It would be disrespectful to answer otherwise.'

Something in her expression shifted — not dramatically, but perceptibly, in the way of small adjustments that accumulate into significant change.

She left.

He stayed at his desk for another hour, working through the appraisal inquiry from Shanghai, thinking about lot twenty-one, and thinking about the craftsman whose mark he believed he was tracking across the centuries.

'Cao Bao Nian,' he said.

'Yes.'

'When you found the celadon bowl at the estate sale. What made you stop at it specifically? There were many other pieces.'

A pause.

'I am not sure I can explain it precisely,' Cao Bao Nian said. 'The other pieces in the group had a quality of — ordinariness. Not poor quality, but nothing that asked a question. That bowl asked a question.'

'What question?'

'I do not know. That is why I bought it. Because I could not answer it and I wanted to be able to.'

He sat with that for a moment.

'You were beginning to look at objects the way I look at them,' he said. 'Without having a framework for why you were doing it.'

'Perhaps. I did not think of it in those terms.'

'The terms do not matter. The looking matters.' He shut down the laptop — he had learned the sequence: save, close, shut down, wait for the screen to go dark, fold the lid. 'You would have gotten there. You had the right question. You were missing the context that would have told you what to do with the question.'

'I ran out of time before I found the context,' Cao Bao Nian said.

'Yes.' He stood, began gathering his things. 'That is why I am here.'

He walked out of the office and down the stairs — he had stopped using the elevator in the second week, finding that the stairs gave him a transitional space between the focused work of the office and the different attention required outside it — and out into the evening city.

Beijing in late October. The light was failing early now, the air carrying the edge of the cold that would become serious by November. He stood on the pavement outside the building and looked at the street — the traffic, the pedestrians, the layered sounds of a city conducting its evening in ten thousand simultaneous directions.

A thousand years and six weeks.

He was beginning to understand how time worked differently here — not just that it was a different moment in history, but that time itself had a different texture. In Chang'an, time moved with the rhythm of seasons and dynasties and the particular patience of people who measured change in decades. Here, time moved at the speed of market cycles and information networks and the constant acceleration of a civilization that had decided that faster was always better.

He was learning to move at that speed without losing the perspective that came from knowing it was not the only speed at which things could be done.

'Cao Bao Nian,' he said quietly, standing on the pavement.

'Yes.'

'The auction is in four weeks. If lot twenty-one is what I think it is, we will need to be able to bid. What is our current liquidity position?'

Cao Bao Nian summarized the numbers — still constrained, still recovering, but improved by the three weeks of new appraisal work and one significant commission that Lin Jing Huo had secured from a collector in Tianjin.

'Not enough to bid competitively against serious collectors if the price rises significantly,' he said.

'No. Not yet.'

'Then we need to build the case for what the piece is before the auction, not just recognize it during bidding.' He began walking. 'If I can demonstrate what lot twenty-one actually represents before other bidders understand its significance, we can acquire it before the competition understands what they are competing for.'

'That requires you to be right about what it is.'

'Yes.'

'And you are not certain yet.'

'Sixty percent. But the preview will tell me more.'

'And if you are wrong?'

He walked for a moment in silence, past a group of people waiting at a pedestrian crossing, past a food cart with a cloud of fragrant steam rising from it, past a woman walking a dog that looked at him with the particular assessment that animals directed at things they had not decided how to classify.

'If I am wrong,' he said, 'then I will have been wrong, and I will have learned what I missed, and the next assessment will be better.'

'That is a very calm way to frame the possibility of being wrong.'

'Being wrong about clay used to mean a broken pot and a day's work lost. Being wrong about an object here means—' he paused, thinking about it, 'the same thing, essentially. The scale is different. The principle is the same.'

He walked home through the October evening, thinking about glaze marks and workshop conventions and the particular quality of attention that allowed a craftsman to leave a signature in a piece of work that only another craftsman, looking for exactly that signature, would be able to find.

The city moved around him at its characteristic speed.

He moved through it at his own.
