Take the annual sugar and wine party as an example.

The organizer is the relevant local administrative organ or department or association.

Co-organizers are the units invited by the organizers to name, provide material support and enjoy part of the income distribution of the exhibition, usually media units. For example, newspapers provide a certain number of pages to promote exhibitions, free of charge or at a discount, and the organizers will benefit in the end.

The organizer is responsible for the scale design, booth price and venue of the exhibition. Generally speaking, they are professional exhibition enterprises, and they make money by this. Is the real exhibition promoter, operator, organizer, just regard it as a justified cover.

I hope I can help you.
