After receiving the invoice, first check whether there is any problem with the printing of the invoice, whether there is any misspelling or garbled code, whether it is stamped with the special invoice seal, and whether the tax number of the special invoice seal is consistent with the tax number on the invoice. If the above situation occurs, the invoice cannot be used for reimbursement and is not recognized by the tax bureau. It can be regarded as a fake invoice.
