Rather than surveying the chronicle exhaustively, it selects three cases because each saturates a distinct layer of the criminalizing lexicon, allowing the system to be reconstructed from a small but analytically complete corpus. The analysis is organized along three cross-cutting semantic-lexical fields rather than the events’ narrative sequence: prosecutorial verbs (bức, thông, đoạt, hặc tấu), dehumanizing labels and classical allusions (dâm loạn, tụ ưu, chưng), and kinship-term aggravators (huynh thê, đích tỷ, đồng bào nữ), newly identified here. Through etymology, glyph analysis, and historical philology, the study shows each field enacts a mechanism of Xuân Thu bút pháp [the Spring and Autumn brush method]: nhất tự bao biếm and trực thư kỳ sự for the verb field, bất húy for the label field, and chính danh for the kinship field. Historiographical language, the study concludes, does not merely record but actively renders judgment, its ideographic structure carrying inherent sentencing power within a Confucian moral order. Huy Hoàng Nguyễn Minh Hiếu Vũ Minh Anh Vũ Copyright (c) 2026 Thang Long Journal of Science: Van hien and Heritage 5 1 https://science.thanglong.edu.vn/index.php/volb/article/view/357 Truyền kỳ mạn lụcby Nguyễn Dữ has long been regarded as a representative work of medieval Vietnamese chuanqi fiction, while also reflecting the presence and interaction of Confucianism, Buddhism, and Daoism in the intellectual life of its time. However, most existing studies have largely stopped at affirming the synthesis of the Three Teachings without clarifying the internal mechanism through which this relationship operates within the work’s intellectual structure. Approaching Truyền kỳ mạn lục from the perspectives of discourse and the Confucian value system, this article analyzes the roles of Confucianism, Buddhism, and Daoism in constructing the artistic world and orienting the work’s meaning. The findings show that Confucianism functions as the primary frame of reference and the central value system in the organization and interpretation of the narratives, whereas Buddhism and Daoism are selectively received, both providing materials for constructing the supernatural world and being reinterpreted to serve didactic purposes and affirm moral values in the Confucian spirit. In this way, the article helps clarify the mechanism of dialogue and synthesis among the Three Teachings in Truyền kỳ mạn lục, while contributing an approach to the processes of intellectual adaptation and the localization of the Three Teachings in medieval Vietnamese literature. Dinh Son Le Copyright (c) 2026 Thang Long Journal of Science: Van hien and Heritage 5 1 https://science.thanglong.edu.vn/index.php/volb/article/view/405 This article analyzes the poetry collection in illo tempore (Thanh Niên Publishing House, 2024) by Nguyễn Thụy Đan as case study from the perspective of heritage language and cultural connection. It applies a qualitative approach combining close reading with intertextual analysis, grounded in heritage language theory, drawing on the poetry collection itself as the primary source together with several author interviews and secondary critical materials. The article identifies several features of the collection: a dense presence of Sino-Vietnamese vocabulary, word forms bearing the imprint of early twentieth-century Vietnamese, echoes of the Thơ Mới [New Poetry] movement, and multilingual combination. These features suggest that the collection constitutes an intersection between classical East Asian poetry and modern verse. It can be read as a dual project of preservation: preserving both the communal memory of overseas Vietnamese and a layer of poetic language that is gradually receding into the past. in illo tempore is therefore not merely a poetry collection but may be regarded as a heritage of fossilized linguistic layers belonging to the diasporic community. Minh Tran Copyright (c) 2026 Thang Long Journal of Science: Van hien and Heritage 2026-07-25 2026-07-25 5 1 https://science.thanglong.edu.vn/index.php/volb/article/view/311 Death–a human phenomenon that appears to signify an ending, stillness, sorrow, and loss–has nevertheless become a point of convergence and a central category of concern in three major Eastern systems of thought: Confucianism, Daoist philosophy, and Buddhism. Within these three traditions, death is not understood merely as the cessation of human biological activity; it is also considered within philosophical, ethical, and aesthetic categories. This article approaches death as an aesthetic form rather than as a dark and fated conclusion. It examines the conception of death in each system of thought, whose different epistemological foundations and perspectives generate distinct aesthetic values. By elucidating their philosophical depth, the article opens an aesthetic perspective on death at the point where Confucianism, Buddhism, and Daoism meet. It thereby arrives at the following conclusion: in Eastern philosophy, death is not an endpoint but a doorway into the profound dimensions of life, enabling human beings to perceive, confront, and experience the beauty of mortal existence. Bài viết đi sâu vào quan niệm của mỗi hệ tư tưởng với những nền tảng nhận thức và quan điểm khác nhau để kiến tạo nên giá trị mĩ học khác nhau, thông qua việc làm rõ chiều sâu triết lý còn mở ra cách nhìn nhận đầy thẩm mĩ về cái chết mang tính chiều sâu trong sự gặp gỡ của Nho - Phật - Đạo. Từ đó, bài viết đi đến những kết luận mang tính thẩm mĩ: cái chết trong triết học phương Đông không phải điểm kết thúc mà là cánh cửa mở ra những chiều kích thâm sâu của sự sống, giúp con người nhìn nhận, đối diện và tìm kiếm, tận hưởng vẻ đẹp của kiếp người.

By tracing Nguyễn Đăng Thạnh’s literary allusions and borrowings from authors such as Ouyang Xiu and Su Shi, the annotated translation lays a foundation for future research on Cochinchinese intellectual and literary history. It is offered as an annotated translation and philological source study rather than as an interpretive research article.

It examines his early life, education in Europe, pioneering work in complex analysis and Nevanlinna theory, leadership in building Vietnam’s scientific institutions, and his lasting influence on both theoretical and applied mathematics.

Based on an analysis of five Sino-Nom mathematical texts, the study identifies the Temporary Assumption Method as the central reasoning technique used across these versions. The findings reveal a gradual process of localization: early Vietnamese texts retained the original “chicken and rabbit” form, whereas later works replaced the rabbit with the dog, a more familiar and culturally resonant animal in Vietnamese daily life. By the mid-twentieth century, the problem had evolved into a mathematical poem, first recorded in Mathematical Folk Songs (1950), and it has continued to appear in mathematics education from primary to lower-secondary levels. The study shows that mathematical knowledge in Vietnam was not merely transmitted, but also reinterpreted within local cultural, linguistic, and educational contexts.
