Lin Xian listened to VV's description, he could roughly understand what it meant, but he did not know if that was what VV intended to express:
"Speak clearly in human language, what exactly is the situation?"

China's internet, although theoretically connected to the World Wide Web, was in fact separated by a high wall, also known as the Internet Security Great Wall.
To the general public, it seemed as though the main purpose of the Internet Security Great Wall was to prevent them from accessing certain undesirable websites and linking to some foreign pages; but in reality, the Great Wall's functions went far beyond that.
In the real world, there are national borders and national defense.
It's the same in the cyber world.
The Internet Security Great Wall of China is the cyber border of China, like a great wall keeping invasions and malicious acts out, safeguarding China's cybersecurity.
