Signalman misses dinner with his parents

This new year differs from many others for Zhang Dingtao and his new wife as they decided to remain at their jobs during Spring Festival.

The couple work at the Sanjiang high-speed railway station in Liuzhou, Guangxi Zhuang autonomous region.

In charge of signal maintenance, 27-year-old Zhang is proud to be a signalman, as he regards this position to be as critical as an engine driver's to ensuring safety.
