Nation is a noble and sacred word, an eternal theme of all countries in the world, and an unchangeable value pursuit of civilized society. Every five years, Russia issues the National Outline of Patriotism Education to guide people's determination and confidence in loving the motherland and building the country. Every morning, primary and secondary schools in Singapore hold a school-wide ceremony to educate students in patriotism through activities such as raising the national flag, singing the national anthem and reciting patriotic vows in chorus. There is such a lyric in the national anthem of South Korea: "Love our dear motherland with our will and spirit, and dedicate our body, mind and loyalty to her, regardless of pain or joy." At national celebrations in the United States, everyone will recite the oath of "I love this country and defend it". Kennedy's phrase "Ask not what your country can do for you, ask what you can do for your country" is a famous saying advocated by Americans. It can be said that there is not a country in the world that does not advocate patriotism.
