Meet the training guru keeping China on track

"It's really awesome to be a worker here," says Luo Zhaoqiang, from CRRC Changchun Railway Vehicles Co, a high-speed train manufacturer based in Northeast China's Jilin province.

The 47-year-old has worked for the company for 29 years, testing high-speed trains for eight of them, which makes him a well-known expert in the field. When talking about his work as a so-called "high-speed train doctor", his tone changes, lifting his voice.

"Testing is the very last step before the trains roll out. We endow the cars with life, making sure they leave the factory in good condition."
