What is the difference between organizer and organizer? What do they mean?

The organizer is the unit that hosts the event, and the organizer is the unit that specifically handles the event.

Generally, many activities are planned and handled by the organizer in order to be authoritative. To increase the influence, you need to find a superior department or competent department as the organizer. Sometimes if you want to reduce costs, you can find a few co-organizers to provide some support.

For example, the city of Beijing wanted to hold a party, but there were no celebrity resources or professionals, so they paid an entertainment company to do it. The city of Beijing was the organizer, and the entertainment company The company is the host.
