Le Quy Don

(chữ Hán: (; 2 August 1726 – 11 June 1784), , also known by his pen names Doãn Hậu , and Quế Đường was an 18th-century Vietnamese poet, encyclopedist, and government official. He was a native of Duyen Ha village in present-day Thái Bình Province. Alongside Lý Thường Kiệt, Trần Hưng Ðạo, Chu Văn An, and Lý Tế Xuyên, he is considered one of Vietnam's nationalist writers and a revered polymath of the early modern period for the "astuteness of his work and phenomenal productivity."

Life Lê was born in the province of Thái Bình, and lived in the reign of Emperor Lê Hiển Tông. The period of his life was marked by a split between the Trịnh lords of the north and the Nguyễn lords, in the aftermath of an examination system scandal involving his son Lê Quý Kiêt (who was sent to prison for changing examination books), had been ordered south of the Linh Giang River to serve as an official ...As a member of the Trịnh lords' bureaucracy, Lê Quý Đôn was supposed to help restore civil government in a region of Viet Nam that had been separate from the Trịnh lords' control for over two centuries, and facilitate the reincorporation of the southern territories, particularly those controlled by the Nguyễn lords, into the authority of the Trịnh-led northern government.

In 1760, Lê Quý Đôn went to China as an ambassador. He later served as a government official in the ministries of war, finance and public works. He also served as the rector of the National University situated in the Văn Miếu in Hanoi and as Director of the Bureau of Annals. It is said that Lê was traveling with some Qing officials, and along the way they saw a Chinese poem inscribed on a stone palette. Later, one of the Qing officials, to test his merit, asked him if he could remember what was on the stone palette. Lê recited the entire poem, word for word, in Chinese. That earned him a great deal of respect from the Chinese.

Writings Lê Quý Đôn was responsible for a large number of encyclopedic, historical, bibliographical, and philosophical works. It is estimated that he has the largest volume of works among Vietnamese literature using Chinese characters (about 40 series with hundreds of volumes).

The Vân đài loại ngữ (Classified Sayings, 9 volumes) is Vietnam's largest encyclopedia, a landmark in Vietnamese science in the Confucian era. The history Đại Việt thông sử (30 volumes) contains many documents about the Lê dynasty. The Phủ biên tạp lục (Frontier Chronicles) (6 volumes) was a detailed description of Nguyễn territories in Thuận Hóa and Quảng Nam Provinces.

Legacy

Today, one of largest technical universities in Hanoi, Le Quy Don Technical University (LeTech), and many schools in Vietnam are named after him. Most cities in Vietnam have named major streets after him.

Le Quy Don High School in District 3 is the first high school to be established in Saigon, Vietnam. The school was built in 1874 and it has been fostering generation of students up until this day. Despite being over a century old, Le Quy Don High School has still maintained most of its original architecture. The school's location in central Saigon makes it one of the most popular spots for filming.

Finally, "Lê Quý Đôn″ is also the name of a new Vietnamese sail training ship, built in 2015 by the Polish ship yard Marine Projects Ltd. on behalf of Polish Defence Holding in Gdynia. Some of its data: overall length: 65.0 m, breadth: 10.0 m, air draft: 42.0 m, sails area: 1395 m2, propulsion: 880 kW, crew and cadets: 30 + 80 persons.

Literary Anecdote Anecdotally, the young boy Lê Quý Đôn was tested by Scholar Vũ Công Trấn, after visiting fellow graduate Lê Trọng Thứ (formerly Lê Phú Thứ), with the poem titled Rắn đầu biếng học ("Stubborn-headed snake, indolent in study" – a metaphorical rebuke for obstinacy and laziness in learning).

Lê Quý Đôn composed a poem in the classical thất ngôn bát cú form, embedding the name of a distinct snake species into each line as subtle self-deprecating wit, while adhering to rhyme, tone, and structure:

Chẳng phải liu điu vẫn giống nhà! Rắn đầu biếng học lẽ không tha Thẹn đèn hổ lửa đau lòng mẹ, Nay thét mai gầm rát cổ cha. Ráo mép chỉ quen tuồng lếu láo, Lằn lưng cam chịu vết roi da. Từ nay Trâu Lỗ xin siêng học, Kẻo hổ mang danh tiếng thế gia!

English Translation with Line-by-Line Interpretation No lowly water snake, yet true to noble lineage! Meaning: The boy affirms his worthy family background (not of humble or insignificant origin), rejecting any lowly comparison.Stubborn snake-head, indolent in study—no leniency shall be shown. Meaning: Directly echoes the title's rebuke: a "hard-headed" (stubborn) child who is lazy at learning will not be forgiven or excused.Shamed beneath the lamp, coral snake dreads the flame—mother's heart in anguish. Meaning: Under the study lamp (symbol of diligence), the shame of laziness causes fiery inner torment, deeply hurting the mother's feelings.Shouts today, golden-banded roars tomorrow—father's throat grows hoarse from constant reprimand. Meaning: The parents' repeated scolding (yelling today and roaring threats tomorrow) wears down the father's voice, showing the toll of the child's disobedience.Rat snake's tongue versed only in deceit and insolence. Meaning: A glib, smooth-talking nature (like the rat snake's quick tongue) leads only to lies and cheeky behavior.Whip snake's back bears the lash's cruel stripes without complaint. Meaning: The child passively accepts punishment (whip marks on the back), enduring corporal discipline as deserved consequence. Henceforth, buffalo snake of Zou and Lu vows diligent pursuit of learning. Meaning: From now on, like the mighty buffalo snake (symbol of strength), and drawing inspiration from the Confucian homelands Zou (Mencius) and Lu (Confucius), the boy pledges to study earnestly and reform. Lest cobra carry disgrace upon the family's honored name! Meaning: Otherwise, he risks bringing shame ("cobra" plays on "bearing a tiger" or carrying burden) to the entire family's reputation and legacy.

Overall Interpretation of the Wordplay This poem turns paternal admonition ("rắn đầu" – hard-headed laziness) into profound humility and promise of redemption. Each line integrates a snake reference (liu điu = water snake, rắn đầu = stubborn snake-head, hổ lửa = coral/tiger-fire snake, mai gầm = golden-banded/roaring snake, ráo = rat snake, lằn = whip/striped snake, trâu = buffalo snake/hổ trâu, hổ mang = cobra), weaving reptilian imagery with themes of indolence, parental sorrow, deserved punishment, and vowed scholarly diligence.
