History education is the best national education and indoctrination. History is the root of the nation and the most basic conscience of China people, that is, the "China Heart" recited in the lyrics; Familiarity with history is the irreplaceable and deepest source of living water for the Chinese nation to maintain cohesion and identity. Therefore, we must attach importance to history education, plant ethnic roots in people's hearts from an early age, and never forget "I'm from China" like Ji Hongchang.
