Online Conference Participation and Presentation Instruction

To join conference: We will use Tencent Meeting as the online conferencing tool. If you are not in the mainland of China, you need download the international version, that is, Voov. Windows system and Mac OS are preffred for Tencent/Voov Meeting. Please install Tencnet Meeting/ Voov in your laptop. Just simply copy the conference room number into theTencent Meeting/Voov, and enter the correct password, then you are in. The conference room number and the password will be sent to the corresponding author of of each successfully registered paper through email. For the authors who have not yet registered, please complete your registration as soon as possible.

 

 

To make presentation: Your presentation is limited in 20 minutes with Q&A included. Please make your powerpionts ready before your presentation. When you make presentation, click the "Share" button, and choose to share the whole screen (recommended). We will be able to see your powerpoints. Then just go ahead to do the presentaiton as regular times! We highly recommend you to do live presentations so that we can have better communication, pre-recorded video should be the last choice when it is necessary.

 

You can click here to see detailed step-by-step instruction for Voov.
