In the context of China's Great Firewall (GFW), privacy is a crucial issue. The GFW monitors and restricts access to information and social media, putting pressure on freedom of expression and forcing individuals to adjust their online behavior. Users are constantly surveilled, creating an atmosphere of fear and self-censorship. Privacy is not only about personal data but also about the freedom to communicate openly and share information without fear of repercussions. In today's digital world, it is essential to be mindful of privacy and understand the tools that can help ensure online security.
