My family's old house in Shenzhen, China is being preserved due to its cultural heritage. Essentially when my dad was a kid, it was where our water buffalo lived. But when the village turned into a town, and later a city, there was no more need for water buffalo storage, so it got turned into a 2 room house. Now it's being preserved as everything else is has been replaced by high rises and skyscrapers. So the authorities are renting it from us to turn it into a tourist attraction. It will be like the slum equivalent of a stately home.
