I'd like to know anzhen hospital's medical insurance number.

Anzhen hospital, Chaoyang District, Capital Medical University, is a comprehensive third-class foreign student.

This number is in the medical system (known to every social security worker), and it will automatically come out when it is recorded in the system. I don't know why your company wants you to provide it instead of recording it yourself, but now it doesn't matter whether the hospital changes it or not. You can go with a card.
