Matters needing attention in online voluntary reporting

1. Candidates should keep their passwords (printed on the admission ticket) to avoid password disclosure. Students who have lost their admission tickets will be accompanied by their parents to Room 4 10 of the Basic Education Office of the Municipal Education Bureau (No.320, Chazishan Middle Road, Yuelu District) to reissue their original passwords. Learn to change the password yourself.

I suggest you remember and write it down. Students who forget the new password and cannot fill in their volunteers need to go to the information center of the Municipal Education Bureau with their valid certificates accompanied by their parents. If the volunteer information is tampered with by others due to password leakage, the candidates and parents are responsible.

2. After completing volunteering, you must first use the "Save Volunteer" button, and then click the "Safe Close Exit" button. Don't click the "X" at the top right of the screen to quit.

3. Being idle for 10 minutes after logging in to the system (or not touching the keyboard and mouse for 10 minutes after opening the page) will be forced to exit the system, and the operation will be invalid. Failure to fill in the volunteers on time is regarded as giving up the volunteers.
