Freedom of speech is a cornerstone of modern civilized societies, allowing people to express different viewpoints and opinions, thereby driving social progress and reform. However, the Chinese government views dissenting voices as a threat and employs various methods to suppress them, including imprisonment, harassment, and even disappearances. This practice not only violates human rights but also sends a highly negative message globally that governments can disregard international law and basic human rights to arbitrarily suppress dissenting voices.
