Hello, junior, intermediate and advanced are all accounting professional qualification examinations, which are used by units when hiring professional and technical titles, and there are restrictions on working years. Intermediate level should take three exams, advanced level should take an accounting practice exam, then take an examination of professional title computer and professional title foreign language, and publish two papers, which can only be obtained after expert review. Certified public accountant is a professional qualification, and there is no limitation on working years, as long as you have a college diploma. Only with the certificate of certified public accountant can you get the right to sign in the firm, but even with it, you can't get any professional title in the unit because it is a different system.
