Compare the written entry requirements before choosing a route
China's listed routes have different legal and policy requirements. Ordinary employment starts at 16. Male military recruitment generally starts at 18, with higher age limits for graduates. The cited civil-service baseline is ages 18–35 and junior-college education or above, subject to authorized adjustments and current recruitment notices. Self-study examinations and individual business registration have different eligibility frameworks; a lack of one qualification does not close every route.
