There were packs of countryside folk roaming the streets this morning, painting the bottoms of all the trees in Kunming white. I've seen this before in China but have never been able to find the reason for it all. Some Chinese friends say it's to keep the trees warm in the Winter (but then why stop painting so low?), while others say it's to prevent insects climbing the trees (but then why paint them in the Winter when there are no insects around?). When I lived in the countryside, I was told it was to help the cars see the edge of the road at night, but that can't be true in the well-lit city here? Presumably someone pays for it, so there must be a reason? My Chinese teacher, Cathy, has said she'll ask around and see if anyone has any idea why this happens every year.
