The ways for Yunnan college students to stop participating in medical insurance are as follows:

First of all, you can choose to go offline, and you need to bring your ID card and medical insurance card to the local social security bureau for medical insurance suspension procedures. Secondly, you can also choose to apply online. You need to download and log in to Yunnan Medical Insurance Service APP, select the business application on the service page, then click Cancel Registration, fill in the relevant information and submit it.
