This reminds me of the time when I had to wash my school shoes each weekend so that they are sparkling white to start the school week.
I see that this is still done today. White canvas shoes are usually less than white at the end of each week. Although these days, some schools assign black ones.
What amused me was how these shoes are arranged on this window ledge for drying. I remember putting mine against the side of the small longkang by the car porch to dry.
