The Great Unity is an ancient ideal that promotes a utopian society described in literary works like "Essays on Anthropology" by Qiu Peiran. It emphasizes faith, education, and support for marginalized groups while unleashing the potential of youth. Balancing progress with preserving cultural heritage is key to sustainable development in regions like Sa Pa, as shown in the photobook "Kinh Wave - The Development Wave (2017-2022)". The Great Unity can guide us towards a brighter, more inclusive future by emphasizing harmony, stability, and unity.
