What is real courage?

Continuous heavy rain hit Mianyang in Southwest China's Sichuan province on Thursday. To resist the flood and prevent the bridge on the Fujiang River from being damaged, two heavy-duty cargo trains stayed on the bridge for six hours.

The train drivers were 26-year-old Zhang Qiang and 28-year-old Chen Long. With torrential rain, flooding and an unstable bridge beam, the task was extremely dangerous. It was a severe test of the drivers' professional and psychological capabilities.

"The rising flood waters were around the train when I drove it to the bridge. I was under great pressure but didn't have time to be scared. All I wanted was to take control of the train and keep the bridge safe," one driver said.
