The Tongjiang-China-Russia-Heilongjiang Railway Bridge is an important node on the east channel of the China-Europe trains along the Belt and Road Initiative. The bridge is guarded by a group of young people, with an average age of only 26 years old.
The hardest part of each inspection is to inspect the riverbed of the bridge. It takes 40 minutes for the bridge and tunnel workers to reach the measurement point on foot. With a temperature of minus 30 degrees Celsius, the body temperature is even lower.
