In the winter of 1443, Sejong, suffering from eye disease, made the twenty-eight letters. Memorials were submitted against them, and the king and queen went together to Chosu-ri to treat his illness. In the third month of 1446, Queen Soheon, who had shared thirty-eight years with him, died before him, and in the ninth month of that year the Hunminjeongeum was completed. Praying for the queen’s soul, the king composed songs in the new letters — songs of the moon shining on a thousand rivers, the Worin cheongang jigok.

The banks of the Tumen, the northern edge of Joseon.

The north wind blows through the treetops, the bright moon is cold upon the snow,

on the frontier walls ten thousand li away, I stand leaning on my long sword,

a long whistle, one great shout — nothing stands in my way!

— A sijo said to have been written by Kim Jong-seo

The riverbank where he stood leaning on his sword became the edge of the country we know today.

When Sejong’s reign was just beginning, the northern edge of Joseon had not yet been settled.

Many Jurchen tribes lived around the Yalu (Amnok) and the Tumen, and in the border villages the sound of hoofbeats never ceased.

In the southern seas, there were Japanese pirates.

In the sixth month of 1419, on the orders of the Retired King Taejong, 227 ships and more than 17,000 soldiers led by Yi Jong-mu crossed over to Tsushima, the lair of the Japanese pirates.

Yi Jong-muSupreme Commander of the Three Armies

After that, there were far fewer Japanese pirates in the southern seas.

In the winter of 1432, Jurchen horsemen from across the Yalu swept down on the district of Yeoyeon in Pyeongan Province. Many people were killed or carried off.

In the fourth month of the following year, Choe Yun-deok, Military Commander of Pyeongan Province, led 15,000 troops across the Yalu and struck the Jurchens around the Pajeo River.

Choe Yun-deokMilitary Commander, Pyeongan Province

Along the upper reaches of the Yalu, four districts were set up one after another.

Yeoyeon, Jaseong, Muchang, Uye — the Four Commanderies.

The banks of the Tumen in the northeast were farther still, and colder. The king entrusted that land to Kim Jong-seo.

Kim Jong-seoGovernor of Hamgil Province
SejongBuild fortresses along the river
and settle the people there.
That is the edge of our land.

Kim Jong-seo went to the banks of the Tumen. For many years after that, he guarded that land.

Along the river he built fortresses and set up districts. Hoeryeong, Jongseong, Gyeongwon, Gyeongheung, Onseong, Buryeong — the Six Garrisons.

People of the south left house and home and moved to the snow-covered far north.

The Four Commanderies on the upper Yalu, the Six Garrisons along the Tumen.

The courses of the two rivers joined and became a single line.

The northern edge of the country we know today was drawn then.

The road away from home was long and cold. The king lightened the taxes and corvée labor of the people who moved north, and he also gave official posts to people of that land.

ChildFather,
how much farther?
DadUntil we
see the river.

The king is said to have spoken of Kim Jong-seo like this:

SejongEven with me, without Kim Jong-seo
this work could not have been done;
even with Kim Jong-seo, without me
it could not have been pushed through.

While fortresses rose along the two rivers, the king grew old.

His eyes were so sore and inflamed that he could hardly see what was before him, and illness had sunk deep into many parts of his body.

And in the spring of 1446,
the queen who had shared thirty-eight years with him went on ahead.

The king buried the queen west of the tomb of his father, King Taejong. And beside her, he had one more chamber made, where he himself would lie.

Two chambers in one tomb. One of them was empty.

In the seventh month of 1448, the king announced that he would rebuild a small Buddhist chapel beside the palace. His ministers stood in his way, asking what such a thing was doing in a Confucian kingdom, and the students of the Seonggyungwan, the national academy, emptied their school and walked out.

According to a story handed down, when even the scholars of the Hall of Worthies (Jiphyeonjeon) had all walked out, the king called for his aged state councillor, Hwang Hui, and said to him:

SejongThe scholars of the Hall of Worthies
have abandoned me and gone.
What am I to do now?

Hwang Hui, it is said, went to the scholars’ homes one by one and brought them back. That winter, the chapel was built after all.

At night, the old king would open a worn book. From between its pages, a folded sheet of paper slipped out.

Queen SoheonPlease spare your eyes.

17th day of the 2nd month, 1450.

The king closed his eyes at the home of his youngest son, Grand Prince Yeongeung. He was fifty-four.

He had been king for thirty-two years.

The historian wrote: “People of that time called him the Yao and Shun of the East.”

In the sixth month of that year, the king lay down in the empty chamber beside the queen.

For four years, that place had stood empty.

The moon rose.

Over the Yalu, over the Tumen — over the wall where Kim Jong-seo had stood leaning on his sword.

As the king had sung, one moon shone on a thousand rivers.

And over one tomb.

The king drew the edge of the country along two rivers.

And the end of his own life, he drew beside one person.

In 1469, their tomb was moved to what is now Yeoju in Gyeonggi Province. Beneath one mound, the two of them still lie side by side.

Twenty-eight years she lived as queen. Twenty-eight letters the king left behind.

In those letters, to this day,
we write a letter to someone.

History Notes

The scenes in this story are based on these records and sites.

  1. The Four Commanderies and the Six Garrisons

    Under Sejong, the Four Commanderies of Yeoyeon, Jaseong, Muchang and Uye were set up along the upper Yalu (Amnok), and the Six Garrisons of Hoeryeong, Jongseong, Gyeongwon, Gyeongheung, Onseong and Buryeong along the lower Tumen. In the 4th month of 1433, Choe Yun-deok, Military Commander (dojeoljesa) of Pyeongan Province, crossed the Yalu with 15,000 troops and struck the Jurchens around the Pajeo River, and Kim Jong-seo, who became Governor of Hamgil Province at the end of that year, set up garrisons along the Tumen over many years. The land was held through resettlement (samin), which moved people from the south to live there, and through the system of local-born officials (togwan), which appointed people of the region as officials. The Four Commanderies proved hard to defend and some of them were abolished under Kings Danjong and Sejo, but the northern border of today, linking the Yalu and the Tumen, took shape at this time.

  2. Tsushima Expedition

    In the 6th month of 1419 (the 1st year of King Sejong), Yi Jong-mu led 227 warships and more than 17,000 soldiers against Tsushima to wipe out the base of the Japanese pirates (waegu). The decision was made by the Retired King Taejong, who still held military authority. Joseon later concluded an agreement with the lord of Tsushima that allowed trade only at designated ports (the Treaty of Gyehae, 1443).

  3. Kim Jong-seo and “The North Wind Blows through the Treetops”

    Kim Jong-seo (1383–1453) became Governor of Hamgil Province at the end of 1433 and later also served as its Military Commander, leading the opening of the Six Garrisons over many years. “The north wind blows through the treetops, the bright moon is cold upon the snow…” (a hogiga, or song of bold spirit) has come down as his work in later sijo anthologies such as the Cheonggu yeongeon. Gin param means a long whistle. The words Sejong is said to have spoken, “Even with me, without Kim Jong-seo…,” appear in the unofficial history Irwollok and have come down through works such as the Gukjo myeongsin eonhaengnok (they date from around 1440). In 1453, three years after Sejong’s death, Kim Jong-seo was killed in the Gyeyu Coup launched by Grand Prince Suyang (King Sejo).

    Two Chambers in One Tomb: Yeongneung

    When Queen Soheon died in 1446, Sejong had a royal tomb built on the hill west of Heolleung, the tomb of his father, King Taejong, and decided on a single mound with two chambers (dongbun isil). On the 19th day of the 7th month of that year, the queen was laid in the east chamber, and the west chamber was left empty as a susil, a chamber prepared during one’s lifetime, for the king himself. Sejong was buried in that chamber on the 12th day of the 6th month of 1450, and in 1469 (the 1st year of King Yejong) the tomb was moved to what is now Yeoju in Gyeonggi Province. In 2009 it was inscribed as a UNESCO World Heritage Site together with the Royal Tombs of the Joseon Dynasty, 40 in all.

  5. The Palace Chapel and the Hall of Worthies

    In the 7th month of 1448, Sejong announced that he would rebuild a Buddhist chapel (the Naebuldang) northwest of the Munsojeon shrine hall inside the palace. The reason recorded in the Veritable Records was that the old chapel at the Munsojeon had been pulled down in the course of a relocation and never restored. The censors, the ministers and even Chief State Councillor Hwang Hui opposed it, and the students of the Seonggyungwan gave up their studies and left, but Sejong did not give way and completed the chapel in the 12th month of that year. The story that, when even the scholars of the Hall of Worthies left, Sejong said to Hwang Hui, “The scholars of the Hall of Worthies have abandoned me and gone — what am I to do?” and that Hwang Hui went around to their homes and brought them back is not in that year’s entries of the Veritable Records; it comes down in Jo Gwang-jo’s recollection of 1518 (Veritable Records of King Jungjong) and in a recollection of 1727 (Veritable Records of King Yeongjo). Many link it to the state of mind of a king who had lost his queen and two sons one after another.

  6. What We Imagined

    The scene in which the old king takes out the queen’s note that he had tucked into the Guso sugan (continuing what was imagined in Episodes 83 and 86), the words the king spoke as he sent Kim Jong-seo off, and the words of the family moving north are not in the records; they are imagined. What Sejong said of Kim Jong-seo and what he said to Hwang Hui at the time of the Naebuldang are stories that come down not in the Veritable Records but in later records.
