The agreement between many exhibition organizers and exhibitors is just an "exhibition notice". This is not enough. An exhibition contract should be a complex of many agreements, or even a complex of many contracts. The following are the relevant documents listed in a relatively successful medium-sized exhibition: 1. Exhibition application form 2. Fascia and conference catalog receipt 3. Conference catalog and media advertising receipt 4. Hotel reservation receipt 5. Conference receipt 6. Progress List of museum exhibits and equipment list 7. Application receipt for business tourism inspection 8. Application receipt for aquatic industry investment promotion meeting 9. Application receipt for special booth production 10. Visitor invitation letter 11. Online publicity receipt 12. Item rental receipt 13. Quotation form 14. Advertising price list 15. Quotation for rental items 16. Exhibition venue map 17. Other exhibition precautions In addition, in addition to providing necessary service facilities, exhibition organizers should also have other obligations and responsibilities towards exhibitors. For example, the "Notice on Strengthening Trademark Management During Foreign Economic and Trade Exhibitions" stipulates that if trademark infringement occurs during the exhibition, the organizer should promptly assist the trademark owner to stop it, and make trademark infringements and trademark disputes clear and the handling situation, and notify the relevant group organizing units; for organizers or group organizing units that fail to conscientiously perform or shirk their trademark management responsibilities or neglect their duties, exhibitors can report to the foreign trade department at any time.
