The sliced red potatoes are sun-dried during the day and collected in the evening.
If the nightly dew falls on the potato slices, they could easily mold, so they must not be exposed to rain.
A bunch of children, who had either just gotten out of school or did not attend, plucked up the potato slices from the ground with their big and little hands, filling their bamboo or willow woven baskets, then dumping them into larger bamboo containers, before returning to pick up more slices.
Jiang He, Zhang Erya and a group of orphans hurried here and there, with Feng Qingxue assigning them work points according to Wang Zhenguo's suggestions.
At sunrise the next day, the gathered potato slices would be spread out on the ground to continue drying. This process would be repeated in the evening.
They repeated this every day tirelessly, until the potato slices were completely dry.
