For business purposes, I attended some international exhibitions in high-tech industry in different countries.
CES is no doubt the No.1 exhibition in high-tech industry. The exhibitors are international, and the audience are international too. Businessmen and professionals from all over the world gather in Las Vegas, USA in January every year for CES show. CES kind of serves as the vane of high-tech industry for the year. Almost every audience attending CES cherishes business purposes. There is no wandering guest in CES because the population in Las Vegas is not large.
Some exhibitions held in China are called “international exhibitions” but the exhibitors are local, and the audience are local too. So are some exhibitions held in Japan. It is not worth visiting such exhibitions.
