Yi Chang-su married again with Lady Ryu when his first wife died early without children, and Bingheogak was the youngest daughter born between them.
Bingheogak had an older brother, Yi Byeong-jeong who was also the son-in-law of Jo Jae-ho, who was well-known at the time, and served as Yijopanseo and Hong Mun-gwan Jehak.
[4] Ryu Han-gyu, the older brother of Bingheogak's mother, married Yi Chang-sik's daughter for the fourth time after losing his third wife.
She also wrote poems and various kinds of writings well, and was also called a female classical scholar (女士) by people around her.
"[10] Judging from these facts, it is presumed that the study of Seo Yu-bon was similar to the school style of the family.
After passing Saengwon-si(A Type of Gwageo) at the age of 22, he applied for liberal arts, but continued to fail.
Moreover, in 1806, his uncle Seo Hyung-soo was involved in administration of the major criminal cases such as murder and high treason and went to exile, and the family collapsed at once.
[6] At that time, his younger brother Seo Yu-gu, who was a vice-president of Hongmungwan, was also imprisoned in Hyang-ri [ko].
[13] Bingheogak wrote in the preface of the 'Gyuhapchongseo' about this time, "I went out to love with my husband in Samho(The Current Location is Mapo) administration and did housework to find all the writings that were needed in daily life and buried in the mountains."
"[6][16] The contents of the 'Gyuhapchongseo' are divided into Jusaui (酒食議), Bongimcheuk (縫紝則), Sangarak (山家樂), Cheongnanggyeol (靑囊訣), and Sulsuryak (術數略).
'Bongimcheuk' contains all kinds of miscellaneous goods such as how to make clothes, how to dye them, embroidery, silkworm rearing, how to fix dishes, and turn on lights.
[15] Gyuhapchongseo not only described the contents in detail and clearly, but also wrote the name of the book cited in small letters on each matter.
In addition, she added her opinion and called it a 'Sinjeung', and at the end of each item, the results of her own implementation were revealed in small letters.
[4] CheongGyuBakMulGi[2] It is a women's encyclopedia written by Lee Bingheogak, the wife of Seo Yu-bon, a practical scholar during the reign of King Yeongjo of the Joseon Dynasty.
In addition, various materials such as the sun and moon, the sea, tide, alcohol, and calligraphy are recorded in Korean.
