The Vietnamese word "cầu chui" refers to a specific type of structure known as a "viaduct" in English. A viaduct is a long bridge that carries a road or railway over a valley, river, or other obstacles. "Cầu chui" can also describe a tunnel-like bridge where vehicles pass through an arch or a passage under a roadway or rail.
In more complex discussions, you might encounter "cầu chui" in terms of engineering or architecture, where you could discuss its design, material, and impact on the landscape.
While "cầu chui" primarily refers to a viaduct or tunnel-like bridge, in some contexts, it can suggest the idea of "squeezing through" or "navigating under" obstacles, particularly in a figurative sense.
