During the exhibition time, all goods can’t enter the main entrance, but the back door of loading area. If goods leave the exhibition hall, they must have the release pass that organizers issue.
In order to protect exhibits, exhibitors should deliver goods to booths on time and according to the quality. If Hall and organizers can’t receive exhibits, exhibitors should store the goods into your logistics company, and don’t deliver goods directly to the hall or organizers. And the hall and organizers are not responsible for the result of losing exhibits.
