The wording is confusing, but I believe the Zhengzhou International Land Port is 50sqkm, not the factory. That also fits the numbers they're giving [1]: "Zhengzhou International Land Port Project announced ——total area of around 50 square kilometers", and that includes a lot of "open-air warehouse" (parking lot). It's still massive, but not quite as crazy.

Agreed, the factories clearly aren't the same size as Manhattan.

		But as a comparison of scale, both the airports in Denver and Dallas-Fort Worth are larger than Manhattan (27 mi2 or 70 km2). https://en.wikipedia.org/wiki/Dallas_Fort_Worth_Internationa.... While that is a ton of activity (and empty space, if you have ever seen those airports), the Big Apple might not be the best reference for scale.
