Affected by the coronavirus, many people choose to work at home. The opportunities for companies to conduct long-distance meetings have increased correspondingly, and the number of users of some video conferencing programs has increased rapidly in the past few months. Facebook also took this opportunity to launch a new service called “Messenger Rooms”. Facebook users can create a video conference room and invite others to participate in the conference. A conference room can accommodate up to 50 people, and it also provides a way for non-Facebook users to enter the conference.
