How many years is the validity period of Tianjin collective account?

Collective accounts are generally settled in one unit. You have worked in the unit for a long time. Resignation or marriage, the account is taken away, and generally there is no validity period. Only by buying a house and moving the collective households to individual households can they be considered as official households in Tianjin, otherwise they may be cleaned up at any time. There are collective households in Tianjin, but I don't work in Tianjin. These people will always be the focus of cleaning up. I don't plan to work and live in Tianjin, I just want to settle in Tianjin, as long as my children can take the college entrance examination in Tianjin. Is this feasible?

"Staying in Tianjin" can be said with certainty: such an approach will definitely not work, and simple college entrance examination immigrants will definitely not work. If you just stay as a collective household, you may be cleaned up at any time. See the population policy of Tianjin Public Security Bureau for details:

Tianjin Public Security Bureau has responded to the situation that "there is no job in Tianjin, and there is no house in Tianjin's name": collective hukou personnel who have no legal permanent residence in this city (Tianjin) and are not employed in this city should move out of this city in time.
