Roadshow was a stranger two years ago, and now it has become a frequently used word. As soon as this new publicity and promotion model appeared in China, it not only attracted the attention and favor of listed companies, brokers and investors, but also aroused the widespread concern and strong interest of other enterprises. They imitated the roadshows in the securities industry to publicize and promote the products of enterprises, forming a popular "roadshow" for enterprises. Roadshow has not only been successfully transferred by enterprises, but also its concept and connotation have been changed and extended, and it has become a live event including press conference, product launch conference, product display, product trial, preferential sales, trade-in, on-site consultation, lottery, gift delivery, prize-winning quiz, karaoke competition, cultural performance, game competition and so on. Nowadays, many enterprises' products or services are in the form of roadshows, and they actively promote their products through face-to-face communication with consumers.
