Candidates who take the exam need to check the bill option when signing up for payment. The exam fee bill will be distributed to the candidates' mailbox in the form of electronic bill after the exam, and candidates can download and print it themselves. Individual candidates who did not ask for an invoice during the registration period must call the examination service hotline 021-61165438 within 30 days after the end of the examination, and will not accept candidates' requests for reissued invoices after the deadline. 890
