This is the remote heart of the desert, where few people set foot.
Scorching sun burns, wind roars, but extreme nature can’t stop the builders.
Steel pipes stretch across the desert, welding sparks shine in the sand.
From surveying and setting out, to trenching and pipe laying,
From assembly, welding to anti-corrosion treatment,
Every procedure is strict, every detail is perfect.
We fight desolation with perseverance, build roads with sweat.
Let the steel dragon cross the desert and Gobi,
open the lifeline for energy transmission.
Salute to every engineer and worker who dedicates in harsh conditions.
You are the brightest light in the desert,
the solid strength of the country’s infrastructure!
