Can I apply for Taixing 4050 social security subsidy when I pay social security in Yangzhou?

You can't. Social security subsidy policy is a policy of territorial management, and local finance issues social security subsidies to 4050 and 4555 personnel. If people from other regions apply for reimbursement of social security subsidies in this region, it will occupy the limited funds of local finance and affect the reimbursement of social security subsidies for 40,504,555 people in this region. So you can't apply for 4050 social security subsidy in Taixing, but you can apply locally in Yangzhou.
