It remind me of ancient Chinese saying "普天之下，莫非王土，率土之滨，莫非王臣", that means "all land belong to the king in the kingdom, all men are servants of the king in the kingdom"
It also reminds me of 天高皇帝遠 (the sky is tall and the emperor is far), which has a somewhat contrary meaning: as you get further from the capital, rules are looser.
I like that, but I think the sky is full of cameras and drones and the Emperor's minions see all.
