In order to prevent the uncertainty of online meeting like connection lost or server down, we added backup meeting room for each session. Please refer to the following steps if you meet the problems above.

1. Try to use the same VooV ID to login the meeting room for several times;

2. If it doesn’t work, please use the backup VooV ID to login a new meeting room for your session.

3. If there are still problems, please send email to ieis2020@bjtu.edu.cn or watch your email to receive the latest notice for resolution.
