Each day we were fully occupied and had scant time for rest ... When we arrived at a destination, we would hasten to a hotel to unpack and immediately set out on a tour of observation. We spent days on trains with screaming wheels and screeching whistles, careering through billowing clouds of smoke amid belching flames and the smell of iron. Soot and smoke caked our bodies and flew into our eyes. When darkness fell and we reached our hotel rooms, we scarcely had time to wipe off the dirt before it was time for the next banquet ... No sooner did we go to bed at night than it was time to wake up, with representatives from the next factory awaiting us.
