Credit cards must be at least 18 years old. Those who have a fixed income every month can apply with their ID cards and income certificates. In principle, students below the university level are definitely not allowed to apply. At the university level, most students are 18 years old, and some schools will cooperate with banks to apply. When I was in college, our school applied for a local city credit card with a limit of 3000, but most of my classmates didn't activate it. You can contact the Credit Card Center of CITIC Bank to see if it is an application in theory.
