Witness of change

A decade after the Wuhan-Guangzhou high-speed corridor started to function, a leading engineer recalls the journey, Zhao Ruixue and Liu Kun report.

Xu Keliang is a man of medium height and tanned skin and wears glasses like many others in China. His work as a leading designer of the country's most complex high-speed corridor distinguishes him.

Sitting in his office in Wuhan, Central China's Hubei province, the engineer says he has taken on challenges at work, without a thought of ever giving up.
