How many pigs were there in China during the warlord era?
I came across the wonderful site Strange Maps, and one of their offerings was a 1922 map of world hog production
The text says that this is a map of industrial-scale pig breeding. China seems a bit over-represented here. Yes, every farm in China should have a couple pigs. So should every farm in Ohio and Korea, but the densities there seem much lower, and it can’t just be population. Were Chinese really eating all that much ? Or was there a big export industry? Either would be interesting as the first would be a sign of a surprising prosperity, and the later a sign of China getting an export industry right in the 1920s. Does anyone know if there is anything out there on Late Imperial/Republican pigs?
