In China, video calls are monitored!

All websites and apps operated on the internet, especially instant messaging platforms, prioritize content censorship.
All videos, audio, images, and text must be recognized in real-time, retain network logs, be capable of interception promptly, and have backdoor interfaces for monitoring.
These are legal requirements; failing to meet these four points constitutes illegal operation, and companies may be fined, responsible individuals may be detained, and related software may be taken down or shut down.
Surprisingly, many users are unaware of this, so I’d like to add a few more words.
Content censorship is explicitly mandated in the "Cybersecurity Law of the People's Republic of China" and the "Data Security Law of the People's Republic of China."
Due to limitations in computing power and manpower costs, there is a phenomenon of selective enforcement through strict legislation.
But everyone must understand: the internet is not a lawless zone; do not post illegal information online.
Some things are insignificant when not weighed, but once weighed, even a thousand pounds cannot hold them.
Remember, what protects you is only your insignificance.
