Reporters went to the "backside" of the Lanzhou Railway Spring Festival Transport to reveal the fantastic journey of washing train bedding. 8 washing machines, 6 dryers, ironing machines, folding machines and a washing dragon system were running for more than 10 hours a day.

During the Spring Festival travel rush, more than 150 workers in the factory worked three shifts, sorting, washing and packaging more than 45,000 pieces of quilts, pillowcases, sheets and other bedding items every day.
