The Zhongguancun Forum exhibition opened to the public in Beijing's Haidian district on Saturday.

More than 500 companies from home and abroad took part in the exhibition this year.

This year's forum highlights the application of new technologies, products and materials, organizers said. Nearly 30 technology products will be presented in the forum's five aspects — intelligent services, scientific and technological epidemic prevention, on-site effects, online forums and interactive experience.
