Creating prejudice and hostility among people towards a particular ethnic group or group is extremely wrong and harmful behavior and should not be implemented, so there is no so-called “effective propaganda method” to promote this undesirable purpose. All ethnic groups and groups should be treated equally, justly and inclusively. Advocating a diverse, harmonious and mutually respectful social environment is the foundation for building a better world. We should resolutely oppose any form of prejudice, discrimination, hate speech and behavior, and work together to promote unity, understanding and cooperation between different ethnic groups and groups. It is the responsibility and obligation of each of us to maintain the unity and unity of all ethnic groups and promote the harmony and stability of society.
