Collective hukou depends on whether it is handled by the employer. If it is handled by the employing unit, it shall be transferred out in principle. If it is handled by your own talent, you can continue to scream. The so-called mobile custody means that you are in a useless unit, and talents exercise their personnel management authority to handle family planning and political examination abroad. Going back to your hometown will only happen when you are newly employed, and it will not happen at other times.
