　　On the 8th, at the 2021 China International Digital Economy Expo (referred to as "Digital Expo") held in Shijiazhuang, Hebei, a special exhibition with the theme "From "Half Radio" to "Cloud Supervisor"" is on display.

From "half of radio stations", old phones in the Republic of China, to the other end of the 5G+AI time folding technology and other industry application scenarios, a "dialogue" spanning nearly a hundred years is being staged.

　　According to Zhou Xingyun, the person in charge of the exhibition site and the technical director of the government and enterprise customer department of China Telecom Co., Ltd. Hebei Branch, in 1930, the Chinese Workers and Peasants Red Army seized a radio station of the Kuomintang army in the first anti-"encirclement and suppression" battle in the Central Soviet Area.

At that time, the Red Army soldiers didn't understand it and broke the transmitter, leaving only the receiver.

It was this "half radio station" that opened the history of China's red telecommunications.

The times are developing rapidly. When the new crown pneumonia epidemic broke out in 2020, when Wuhan Huoshenshan and Leishenshan hospitals were started, a slow live broadcast of “cloud supervisors” by hundreds of millions of people gave people a full appreciation of the era of 5G networks and gigabit optical fiber communications. arrival.

　　"This one-hundred-year telecom exhibition is to show the nearly one-hundred-year history of China's telecom industry from zero to take-off from the beginning of the'half radio' to the 5G era." Zhou Xingyun said.

　　In this year's Digital Expo, a total of 486 companies participated in the exhibition, bringing together many well-known companies in the field of digital economy at home and abroad, and cutting-edge digital economy technologies such as 5G, artificial intelligence, industrial Internet, robots, and drones can be seen everywhere.

The "2021 China's Digital Economy Development Situation Report" released at the Digital Expo shows that China's digital economy continues to maintain strong development resilience at the beginning of the "14th Five-Year Plan".

　　In 1950, China's first wired international telephone circuit was opened; in 1982, China's first 10,000-door program-controlled telephone exchange system was opened; in 2009, China officially entered the 3G era, and China's network communications realized from following to catching up; in 2019, 5G The new era of the Internet of Everything has started, and the number of 5G patents in China ranks first in the world... At the exhibition, behind the pictures is the vigorous development of China's communications.

　　Zhou Xingyun, who has been in the telecommunications industry for 10 years, has treasured the history of the development of China's telecommunications industry.

He explained this history to the audience over and over again, and introduced today's cutting-edge concepts and technologies such as quantum communications, cloud and 5G, satellite communications, and smart cities.

　　"The Internet in China is developing faster and faster." At the scene, a citizen of Shijiazhuang, born in the 70s, said with emotion that he had barely seen any communication tools in his childhood and didn't really see the phone until he went to university in 1995.

But in recent years, from phone calls to text messages, emails, to video calls, mobile payments, and artificial intelligence in the digital age, people can clearly feel the rapid development of technology.

　　"Telegram has been far away from our lives, and modern communications have entered the era of cloud and network integration of the "Internet of Everything"." From "Radio" to "Cloud Supervisor", China Communications has gone through the changes of the times.

But whether it is fighting floods, earthquakes, fighting the epidemic, poverty alleviation, and rural revitalization, telecom people always appear in places where they are most needed to ensure smooth communication and provide information services.

　　In the exhibition that day, "half radio" and "5G" exhaled from the audience over and over again, and fixed it into their lens over and over again.

Zhou Xingyun said that this is probably people's commemoration of history and expectations for the future.
