Chữ Hán

Chữ Hán. This term refers to the logographic characters of Chinese script as used historically within the Vietnamese cultural and literary sphere. For over a millennium, it served as the primary medium for official documents, classical literature, and scholarly discourse in Đại Việt and subsequent Vietnamese states, functioning similarly to its role in Korea and Japan. Its adoption facilitated Vietnam's participation in the East Asian cultural sphere and the Chinese classical tradition, while its adaptation led to the creation of the indigenous Chữ Nôm script. The official use of Chữ Hán declined dramatically in the early 20th century with the promotion of the Latin-based Vietnamese alphabet under French Indochina.

History

The introduction of Chữ Hán into the Red River Delta region is deeply intertwined with periods of Chinese political control, beginning with the Han dynasty's annexation of Nanyue in 111 BCE. During the subsequent millennium of intermittent rule by successive Chinese dynasties like the Tang dynasty, the script was institutionalized for administration and Confucian education, as seen in the Temple of Literature established by Lý Thánh Tông. Following the restoration of independence under figures like Ngô Quyền after the Battle of Bạch Đằng, Vietnamese dynasties such as the Lý dynasty, Trần dynasty, and Lê dynasty continued to employ Chữ Hán for court edicts, historical records like the Complete Annals of Đại Việt, and literary works. Its prestige persisted until the colonial policies of the French Third Republic and the rise of Quốc Ngữ reformers like Nguyễn Văn Vĩnh led to its displacement in the early 1900s.

Characteristics

As a logographic system, each Chữ Hán character represents a morpheme, possessing inherent meaning and one or more associated pronunciations. The characters are constructed from a set of basic strokes and follow structural principles such as the radical system, which organizes dictionaries like the Kangxi Dictionary. The standard form used in Vietnam was Regular script, as formalized during the Tang dynasty, which is characterized by its square, balanced appearance. Pronunciation of these characters in a Vietnamese context is known as Sino-Vietnamese reading, which derives from historical Middle Chinese phonology through centuries of linguistic contact, differing significantly from readings in Mandarin Chinese or Cantonese.

Usage

In pre-modern Vietnam, mastery of Chữ Hán was essential for the imperial examination system, which was modeled on the Chinese imperial examinations and produced the scholarly mandarin class. It was the sole script for composing official documents, legal codes like the Hong Duc code, and diplomatic correspondence with neighboring states such as the Ming dynasty and Qing dynasty. Beyond bureaucracy, it was the vehicle for a vast corpus of literature, including poetry by Nguyễn Trãi, historical chronicles commissioned by the Nguyễn dynasty, and philosophical commentaries on Confucian, Buddhist, and Taoist texts. It also served liturgical purposes in Mahayana Buddhist scriptures and temple inscriptions across sites like the Perfume Pagoda.

Variants and styles

Beyond standard Regular script, calligraphic styles such as Semi-cursive script and Cursive script were practiced by scholars and artists, evident in works by figures like Cao Bá Quát. The most significant variant developed in Vietnam was Chữ Nôm, a script that used modified Chữ Hán characters and newly created compounds to represent native Vietnamese words, famously employed in epic poems like the Tale of Kiều by Nguyễn Du. Regional or idiosyncratic character forms sometimes appeared, but Vietnam largely adhered to the orthodox character forms propagated through imported woodblock prints from China, including editions of the Four Books and Five Classics. The clerical and seal script forms found on ancient artifacts like the Mỹ Sơn steles also represent historical stylistic layers.

Influence and legacy

Chữ Hán is the source of the majority of Sino-Vietnamese lexicon, which constitutes a large, learned stratum of the modern Vietnamese language, especially in fields like academia, law, and medicine. Its study remains a specialized academic discipline within Hán Nôm studies, centered at institutions like the Vietnam Academy of Social Sciences. The script's historical presence is permanently etched into the landscape at UNESCO World Heritage Sites such as the Imperial City of Huế and the stelae in Hanoi. While no longer in common use, knowledge of Chữ Hán provides crucial access to Vietnam's pre-modern literary heritage, including the works of Hồ Xuân Hương, and maintains cultural connections within the broader Sinosphere encompassing Japan, Korea, and Taiwan.
