Group 1: Cultural Foundations - The basic cultural foundations of the East Asian world include Chinese characters, Confucianism, educational systems, legal codes, and Buddhism, which have shaped the region's identity [4][5]. - The use of Chinese characters across countries like China, Korea, Japan, and Vietnam has led to the perception of East Asia as a "Chinese character cultural circle," facilitating communication and cultural exchange [4][5]. - Confucianism has played a foundational role in shaping East Asian culture, influencing moral values and social behavior, which remain evident in contemporary society [4][11].
