Lê Thánh Tông
Literature in "chữ nôm" flourished in the fifteenth century during the Later Lê dynasty. Under the reign of Emperor Lê Thánh Tông (1460-1497), "chữ nôm" enjoyed official endorsement and became the primary language of poetry. By this century, the creation of chu Nom symbolized the happy marriage between Chinese and vernacular elements and contributed to the blurring of the literary distinction between "high" and "low" cultures.
