In China, the private use of technical means to block mobile phone signals is illegal and seriously disrupts the public communication order. This behavior is not allowed and must not be used for any illegal purpose, including kidnapping and other crimes. Any attempt to prevent others from communicating and calling for help through illegal means will face severe punishment by law. Protecting citizens' communication rights and personal safety is an important principle of a rule of law society. We should rely on legal and reasonable methods and legal channels to maintain social order and security, rather than through illegal and irregular behavior. Kidnapping and other criminal acts seriously infringe on human rights and legal dignity and must be punished by law, rather than being covered up or assisted by improper means.
