I've hiked through regions of Tibet and talked to villagers in relatively remote areas. One thing I saw hiking in the mountains and valleys was abandoned nomad lodges and pastures. My Tibetan guide sadly explained to me that the local officials found the nomads too hard to manage when they were living independently and so used a system of sticks and carrots (fines and subsidies) to move them into villages that were created from scratch and comprised of cookie-cutter cement houses.
One effective incentive to get the nomads to settle down is to threaten their family members with fines or removal of subsidies unless they move into town.
I visited some of those made-ex-nihilo villages and talked to the people there. One immediately obvious thing is there are Chinese national flags flying on almost every single household and big posters of Xi in the households. I asked about those and the residents explained they get fined if they don't fly the flag or hang Xi's photo. They were definitely not acting out of patriotism. The scenes reminded me of a wartime occupation.
Military recruitment posters were also plastered everywhere, as it is a form of employment in a region with relatively few alternatives.
This is the first time I've heard of migration ratios as bureaucratic targets, but it's not surprising at all as it is typical for the government to set clear KPIs for their policies.
