1. Associations can issue public welfare donation bills, which are vouchers issued by people's governments at all levels and their departments, public welfare institutions, public welfare social organizations and other public welfare organizations to natural persons, legal persons and other organizations that provide donations when they accept donations and use them for public welfare undertakings on a voluntary and free basis.

2. If the Association accepts sponsorship from other institutions or individuals, it may issue ordinary invoices.

The above is how the County Football Association obtained the sponsorship funds from the China Football Development Foundation. I hope it helps you.
