On the day guisi, a diviner for the Shang king Wu Ding once again heated an ox bone and asked whether there would be disaster in the coming ten days.

The cracks appeared. The king examined them and gave his judgment: hardship will come.

On the fifth day, dingyou, news arrived from the frontier: the Tufang had raided the eastern borderlands of Shang and destroyed two settlements; another state had also invaded the fields to the west.

The question, the judgment, and the news were carved on the same ox shoulder blade. The bone is now in the National Museum of China. Only half of it survives, with more than 180 characters still on its two faces.

1. A Question Every Ten Days

On this bone, the royal house asked the same thing again and again over two months: would there be disaster in the next ten days?

The Shang counted days in ten-day periods. When one ten-day period ended and a new one began, they asked again. The frontiers, the fields, and the reports coming and going did not stop because the question had been asked once. That guisi divination happened to preserve what followed.

To the person who carved it, the Tufang raid was the fulfillment of the king's earlier judgment. What today's reader sees is the record-keeping itself: someone asked, the king judged, a messenger brought news, and the carver joined it all together. Whether cracks could foretell a war, the bone cannot answer. But how the Shang understood an event also became the form in which that event survives.

One point in the record deserves a closer look. It says the news of hardship came "from the west," yet what follows reports raids in both the east and the west. The direction from which news arrived and the direction the enemy struck are not the same thing.

2. Asking It Both Ways

The Institute of History and Philology of Academia Sinica in Taipei holds another piece, a turtle plastron.

On the day bingzi, a diviner named Wei asked about the year's harvest on the king's behalf. He asked twice, once in the positive, "we will receive a harvest," and once in the negative, "we may not receive a harvest."

The two sentences are carved on the same plastron, and the characters are filled with red cinnabar to make them stand out handsomely.

The harvest had not yet come. Yes and no were left side by side on a single object.

Paired positive and negative questions were not used only for harvests. On another plastron, on the day xinyou, the diviner Bin asked whether Hua could defeat a certain state. This too is a paired divination. Whether Hua won, the plastron does not say.

3. Written First, Carved Later

Nor was every character cut in a single stroke of the knife.

One plastron at the Institute still carries ink written by Shang hands with a brush. It asks whether, on the following bing day, there would be no favorable rain. The characters were written, not carved.

Two other plastron pieces were broken and later rejoined. Read in full, the inscription says that on the day dingwei, the diviner Yong asked whether it would rain from that day until xinhai. This piece was first written with a brush and then carved with a knife. And the four characters at the start recording the date and the diviner's name were carved on the back.

Look only at the front, and you read only half the sentence.

Shells and bones had to be prepared, with small hollows drilled and chiseled into the back. Heat was applied in the hollows, and cracks appeared on the front. The cracks were read for good or ill fortune; the writing recorded what the divination asked. Knowing the characters is not enough. One also has to look at the burn marks and at both faces to understand how a piece of shell or bone was used.

4. Rainbows, Rain, and a Child

The National Museum also holds an ox bone with nine inscriptions on its two faces, one of which records a rainbow on the day gengxu. It sits alongside inscriptions asking about rain and harvests. When a sign appeared in the sky, it was recorded; whether it would rain in the following days was asked next.

The divination inscriptions also mention solar and lunar eclipses and stars; clouds, thunder, rain, hail, snow, fog, and wind. The Shang watched the sky diligently and in detail.

What they asked on the bones was not limited to harvests and wars. A plastron at the Institute from Wu Ding's reign concerns Fu Hao's childbirth: from the day of delivery, it predicts good or ill fortune and the child's sex.

A woman's childbirth was solemnly carved into the royal record. What she said as her time approached, and whether she was afraid, the shell does not record.

The questions that survive are, first of all, the royal house's questions. How farmers talked about drought, what those who carried the bones were paid, what an ordinary family did when a child had a fever: the bones will not tell us.

5. YH127

After use, some of these bones were buried together in pits; some broke and scattered.

In 1936, archaeologists from the Institute of History and Philology found a pit numbered YH127 at Xiaotun in Anyang, Henan. The turtle shells in it lay in heaps, and after they were removed they were cleaned and rejoined. It was the first oracle-bone hoard excavated by the Institute.

Rejoining often changes a sentence. When two unremarkable broken pieces are fitted together, separated words connect again, and a question with no beginning or end recovers its date. Where the missing half has not been found, the sentence stays incomplete.

What we can read today depends not only on what the Shang wrote, but on what was buried, what survived, and what was dug up again.

6. Epilogue

Back to the ox bone.

On the day guisi, the king said hardship was coming. On the fifth day, news of the Tufang arrived: two settlements destroyed.

And back to the plastron filled with cinnabar. On the day bingzi, the diviner Wei asked: will we have a good harvest? Will we not have a good harvest?

How the harvest turned out that year, the shell does not say. What it keeps is a question solemnly written down more than three thousand years ago, with its two possible directions side by side.
