But if you can, please ask your friends around you for help. Being a volunteer is not that difficult. It's convenient to consult now. Telephone, official website. You can find whatever information you want. Now it's parallel volunteer, which is much simpler than before.
You'd better find someone who does the enrollment work to give you guidance. You can also spend money to buy it, which not only solves the problem, but also establishes a new relationship.
I can also give you some guidance if it's convenient. Haha
