After four years of hard labor, a tunnel under the China-Laos Railway project was successfully drilled ahead of schedule. Stretching 8.84 kilometers long, this single-hole double-track tunnel is named "Heping," which means peace in Chinese. Meanwhile, the under-construction 1,000-kilometer China-Laos railway line is expected to open to the public in 2021.
