It's the first time I've heard that there are exhibitions in the preschool education industry, such as education, and I seldom come into contact with them. Generally, they are exposed to some furniture exhibitions, automobile exhibitions, jewelry exhibitions, high-tech exhibitions and so on. Exhibition information can generally be obtained through exhibition official website, leaflets, street signs, short messages, mass messages and other means. Now in the network era, information transmission is faster, and enterprises and consumers can learn more.
