Definition

1. Verb (archaic):
   • To sound the signal for closing the gates: The act of beating a drum or gong at dusk to signal the closing of a citadel's, city's, or temple's gates. This was a formal, daily ritual marking the transition from day to night and securing the premises.

Usage Examples

• Verb:
  • Mặt trời gác núi chiêng đà thu không. (The sun set behind the mountains; the gong already sounded the gate-closing signal.)
  • Người lính gác có nhiệm vụ thu không mỗi tối. (The guard had the duty to sound the closing signal each evening.)

Advanced Usage

• This term is primarily found in classical Vietnamese poetry and historical texts. It evokes a sense of tradition, order, and the rhythmic cycle of daily life in ancient times.

Variants and Related Words

• Thu quân (v): Literally "to withdraw troops," sometimes used in a broader poetic sense of ending daily activities, but distinct from the specific ritual of thu không.

Synonyms

• To signal closure: To give a sign that gates are being shut.
• To sound the curfew: To announce a time when gates are closed and movement is restricted (closest conceptual synonym in English).

Related Idioms

• While thu không itself is not commonly part of modern idioms, it symbolizes a fixed, irrevocable moment of transition, similar to the English idiom "to sound the knell" for an ending.
