Transcoding mode of health code: On the application page, users can choose to apply for "red code to green code" or "yellow code to green code" and submit the reasons for transcoding application. It usually takes 24 hours for red team to convert to green code. After the user submits the complaint request, if it meets the requirements of changing the complaint code, the system will generally handle it within 24 hours after verification. If there is still no green code after three days, you can call the contact information sent by the page to contact the staff for handling.
