In the face of the still severe global epidemic situation, the "non-fading radio wave" is used to ensure cross-border transmission. smooth transportation.

Although the telegraph has long faded out of people's daily life, it is still indispensable in the field of railway transportation because of its strong density and U disk transfer.
"The railway telegram is an important part of the official documents in the railway system. It is not only a certificate, but also an instruction." A telegram records the passenger and cargo transportation information of the cooperative organization such as the car number, tonnage, and type of goods, and contains 100 to 2000 groups of words not wait.
The Manzhouli International Telegraph Office is responsible for the sending and receiving of international telegrams on the railway and ensures the safety and order of cross-border transportation. It has a history of more than 100 years.
As a traditional means of communication, on the basis of continuing the original operation mode, the equipment, technical means and working environment used by railway international telegraph have changed in the development of the times.
The telegraph is the main equipment used in sending and receiving work. Liu Yanrong, a telegrapher who has worked for 30 years, said: "My master used a four-code telegraph instead. When I went to work, I used a 'big head' computer with a 3.5-inch floppy disk. , the transmission is slow, and the shifting is slow. The times are developing too fast, and now they are replaced by liquid crystal displays and microcomputers, which run faster and display more accurately.”
Affected by the new crown pneumonia epidemic, foreign maintenance engineers have been unable to come to China since 2020. The telegraph operators communicated and learned through video connections, and maintained and repaired the equipment by themselves. It keeps running, and the waves keep running.
As the most mainland port in China, the normal customs clearance of Manzhouli port plays an important role in ensuring the stability of China's foreign trade import and export.
Since the beginning of 2022, the new crown pneumonia epidemic in Manzhouli has been repeated, but the China-Europe train and cross-border transportation have been carried out in a stable and orderly manner.
On the 26th, Liu Zhenying, the foreman of the Manzhouli International Telegraph Office, was on duty. She was engrossed in her work, and as she tapped the keyboard, lines of text popped up on the monitor.
It takes 15 minutes for an international railway telegram to be received and sent, and mastering multiple languages is their basic skill.

"This small piece of paper can't be wrong with a single word." The telegraph operator needs to quickly approve the telegram information. Each telegram must go through three links: self-inspection, mutual inspection and general inspection. The level, acceptance time and telegram content are all correct before sending out. If there is a little error, it may cause problems such as outage and the inability of both parties to pick up the goods normally.
Since Liu Yanrong started working, he has sent and received more than 200,000 international telegrams, without any mistakes or delays. This remarkable achievement is not "the only" in the field of railway international telegraphy. It is their responsibility to be fast and accurate.
At a distance of 9 kilometers from the Manzhouli International Telegraph Office, the China-Europe trains rush back and forth across the border.
In the bursts of whistle, one after another silent radio waves fluttered in the sky.
