You can issue invoices in your own name, but it is usually the seller or service provider who issues invoices on your behalf. If you are a buyer, there is generally no such thing as invoicing. However, you can only invoice in the name of the seller for reimbursement. There is no requirement, that is, the sales invoice is 3%, and the old books may be duty-free products. According to the tax bureau, this invoice can be reimbursed.

My personal advice to you is to find a bookstore and make out an invoice. Just give some money, you don't have to go to the tax bureau so much trouble.
