The digital development of exhibitions is the current trend. Online cloud exhibition will evolve into an indispensable force for exhibition companies with the development of offline industry. Moving offline scenes to online is currently the ideal way. Online operations will become much easier. Consumers can interact with exhibitors in real time. The way of online cloud exhibition can solve people's suffering in communication, but also let them intuitively understand the product information. For example, you can't see an hour glass art product visually from a picture or text message. You don't know all the features, weaknesses, and strengths of the sand glass clock. But live streaming allows you to look at all aspects of the time sand glass decor. Then you can communicate in a timely manner. Therefore, online cloud exhibition will be the ideal way under the epidemic.
