It’s basic 1930s security. In England, all the road names and signage was removed during WW2 to prevent accurate and speedy orientation by any invading force.
But satellites.
However - expect lots of misinformation and foreigners driving on to train tracks etc in China. Also, expect fake roads and camouflage.
China has a deep insecurity about invasion, given that over the centuries each region has invaded the others (bloodily), and then Japan took over in horrid fashion, and broke them into pieces. They sit next to Russia and India, and as they play increasingly powerful games on the world stage (like all powerful countries do), they’re raising ire.
The difference with them is their military is not really capable of defending the country. Yes nukes, but MAD.
