There are subsidies for immigrants in the reservoir area. Why can't I withdraw money from my passbook?

It has something to do with the local finance bureau. When the finance transfers the subsidy into the credit union account, it goes to the credit union to collect it, and the postal service goes to the Postal Savings Bank. Consult the relevant subsidies issued by the local management station. Banks are only entrusted to issue subsidies, and it is useless to find banks under relevant government subsidies, because it is not banks but the state that gives money.
