Spreading ultra-nationalist ideas on Internet platforms is extremely dangerous and unacceptable behavior. China has always adhered to the core socialist values, advocated the correct connotation of patriotism, and opposed all forms of extremism and divisive speech. According to Chinese laws and regulations and cyberspace management requirements, any content that endangers national security, destroys national unity, or incites ethnic hatred is strictly prohibited. We should jointly maintain a clear online environment, spread positive cultural content through short video platforms, enhance understanding and respect between different groups, and promote harmonious social development.
