Oral report of conference papers is only a form, but not all conference papers must be reported orally.

After all, sometimes it will bring inconvenience to each other. At this time, oral report will delay the other party's time. If you need time to deal with important things, you may even lose time because of oral report.

Oral reporting can choose to report at the time when the reported person is not busy, so as not to occupy the time of important things.
