Edit: I've looked up the picture and confirmed these buildings are some of the empty city that China has constructed. I'm not sure what all the downvotes are for...
These buildings have appeared in countless different places. I guess no one's seeing any humor in it....
Edit to add that I'd genuinely like to know where you saw them and inquire if you know any background on them. I'm very interested in the origins of these projects. I feel like I'm in one of the best places to learn from people with first-hand knowledge.
