Bao Si

The signal fires went up along the ridge at dusk, one beacon kindling the next, and the lords of Zhou came at a gallop with their chariots and their armour and their household troops. They found the capital quiet. No raiders on the western road, no smoke but their own. Only a king on his terrace, delighted with himself, and beside him a young woman who had not smiled in months and was smiling now.

That laugh is supposed to have cost a dynasty. Sima Qian wrote it into the historical record around 94 BCE and it has stuck for two thousand years, which is a remarkable return on one joke.

The oldest surviving mention of her is much smaller and much colder. A poem in the Book of Songs, the ode called Zhengyue, carries eight characters that predate every story anyone tells about her: the majestic Zong Zhou, Si of Bao destroyed it. That is the whole indictment. No beacons, no dragons, no explanation. Everything else grew around that line like scar tissue.

What grew around it first was her conception, and it is one of the strangest origin stories in the Chinese record. Late in the Xia dynasty, the account goes, the guardian spirit of the state of Bao took the form of two dragons and came into the royal court, announcing themselves as the two lords of Bao. The Xia ruler divined about killing them and divined about driving them off, and both readings came back unlucky. He divined about asking for their saliva and keeping it, and that one came back well. So the residue was gathered, wrapped in cloth, and sealed in a casket, and the dragons vanished. The casket sat unopened through the fall of Xia, through the Shang, and into the Zhou. For centuries nobody was curious enough to lift the lid.

King Li was. At the end of his reign he had the casket opened, and whatever was inside ran out across the courtyard and could not be scrubbed away. Faced with a stain that would not come off his own flagstones, the king ordered the palace women to strip and shout it down. It turned into a dark lizard and went into the women’s quarters instead. A young servant girl who had taken no part in the ritual met it there. Years later, grown but unmarried, she gave birth. The court was frightened enough to throw the infant out.

There had been a rhyme going round the capital before any of this: mulberry bows and quivers of wild hemp will truly bring an end to the state of Zhou. King Xuan heard it and gave orders that anyone selling such things be seized and executed. A husband and wife trading in exactly those goods ran that night, and somewhere in the dark they heard a baby crying by the road. They stopped, picked her up, and carried her south into the state of Bao. The prophecy the king was trying to strangle put the child into the hands of the only people who would keep her.

She grew up beautiful there. When Lord Xu of Bao fell foul of the law, he offered the young woman as compensation, and King You accepted her and let him go. She entered the harem around 779 BCE carrying the name of the place that had given her up.

The rest of the traditional account is a catalogue of a king losing his grip. She bore a son, Bofu. King You set aside his queen, a daughter of the Marquis of Shen, and disinherited the crown prince Yijiu in favour of the new child. He took her out in his own carriage and brought her back in it, rode out hunting whenever the mood struck, drank steadily, and kept entertainers working in front of him from dark through to the next morning. She sat through all of it without smiling. Men who advised him against any of it were put to death.

Then came the beacons. He had a signal fire and a great war drum set up against raids, and he lit them for nothing. The lords came in from every direction, weapons ready, and stood about in an empty field, and Bao Si laughed out loud. He did it again. He kept doing it. By the time the Marquis of Shen came at him in earnest, allied with the state of Zeng, the Western Yi and the Quanrong, the signal meant nothing to anyone. King You lit the beacons and no one came. They killed him at the foot of Mount Li, took Bao Si, stripped the treasury and left. Yijiu was crowned as King Ping and moved the capital east, and after that the Zhou king was no more powerful than any lord who nominally served him.

Nobody wrote down what happened to her after that.

The power the tradition assigns her is entirely passive and entirely total: a face worth throwing a kingdom at, and a mouth that would not do what the king wanted. She holds no weapon, casts no spell and issues no order in any surviving version. The dragons are in her blood and they do nothing for her. Whatever force she has runs through other people’s decisions, which is exactly why the story was useful to the people telling it.

Its weakness is that the machinery does not work. Beacon systems of the kind described are a much later way of defending a frontier, and the practice looks borrowed back from the Han dynasty and dropped into an era eight centuries too early. The archaeologist Yan Yongqian, digging at the vanished Western Zhou capital west of Xi’an, has said the beacon story was probably fabricated to demonise her and cover up the dynasty’s real problems. Edward Shaughnessy calls her role in the collapse a fairy tale, and suspects it was assembled out of factional infighting at court. Chong Jianrong, who directs the Shaanxi Institute of Archaeology, puts it more bluntly: she was a scapegoat, and when a society fails somebody has to carry it, and in a patriarchal one that somebody is always a woman.

The alternatives are less satisfying and better evidenced. A bamboo manuscript from around 370 BCE, recovered in recent decades and known as the Xinian, tells the fall and its aftermath quite differently from Sima Qian, including a nine-year stretch with nobody securely on the throne. Stalagmite records point to sharp cooling and drought around 2,800 years ago, immediately before the collapse. Li Feng’s study of the period frames the puzzle that all of this is trying to answer: if the Western Zhou really was the golden age Confucius said it was, something had to explain why it came apart, and a bewitching consort was a cheaper answer than a failing system. Yan Yongqian is not even certain she existed. If she did, he notes, one person cannot destroy a dynasty. At a museum near the excavation, the beacon story is still the version on display.

Frequently Asked Questions

Who was Bao Si?

Bao Si was a consort of King You, the last ruler of China’s Western Zhou dynasty, who entered his household around 779 BCE. Her name means “Si of Bao”: Si was her clan name and Bao the small state that handed her over as legal compensation for its lord’s crime. Chinese tradition blames her for the dynasty’s collapse in 771 BCE, though her personal name was never recorded and she is given no words of her own in any version.

What is the story of Bao Si and the beacon fires?

King You is said to have lit the emergency beacons and beaten the war drum as a prank, because Bao Si never smiled and the sight of his lords rushing to an empty field made her laugh. He repeated the trick until the alarm meant nothing. When the Marquis of Shen attacked in earnest alongside Zeng, the Western Yi and the Quanrong, the beacons were lit for real and no one came, and King You was killed at the foot of Mount Li.

How was Bao Si born?

According to the legend, two dragons entered the Xia royal court and their saliva was sealed in a casket that stayed shut for centuries. King Li of Zhou finally opened it, the residue spilled across the courtyard, and it became a dark lizard that entered the women’s quarters. A young palace servant encountered it, later gave birth without ever having a husband, and the abandoned infant was rescued by a fleeing couple and raised in the state of Bao.

Did Bao Si really cause the fall of the Western Zhou dynasty?

Modern scholarship says no. Archaeologists working at the Western Zhou capital describe her as a scapegoat and think the beacon story was invented to demonise her, and the beacon system itself looks like a much later frontier practice written back into the eighth century BCE. Stalagmite evidence points to severe cooling and drought just before the collapse, and the dynasty was already losing control of its regional lords. Some researchers doubt she existed at all.
