Behind these incredible feats of engineering are numerous craftsmen with unrivalled skills and knowledge.
In a bid to better understand the secrets behind China’s technical marvels, CGTN followed these master craftsmen to unveil the stunning work they have contributed towards the Chinese dream!
Xu Liping’s job is to shave off any excess from the explosive powder propellant used on rocket engines. Operating on the most powerful rocket engine produced in China requires superior technical skills and extreme caution, since any extra friction might create a spark, causing the engine to explode. Normally the margin of error when shaving should be controlled at 0.5 millimeters, but Xu can narrow it to 0.2 millimeters. Xu has worked as a gunpowder shaver for 29 years and he continues to make a contribution to China’s space projects.
