Places that meet these basic criteria are in plenty nationwide. The preferential policies and actual conditions in other places are better than yours. Why would anyone go insane and come to your place?
However, although the county leaders have given approval for support, there are still procedures to follow. After all, this is not the era of computers yet, where you can find everything online. Many things still need to be done manually, hence the efficiency is limited.
The simplest example is when you go to the rural police station to apply for an ID card. All the files of tens of thousands of residents are stored there, and a few people are sweating from moving files around.
In addition, all these files are handwritten. In case of unclear handwriting or mistakes in names, you need to go back to the village and get a new proof. Otherwise, you can't even get your ID card.
