“向内凝聚”的统一性追求，是中华文明连续的前提，也是文明连续的结果。在第三集“四海同心”中，来自中国台湾的文化学者高文麒将作为寻访人，去往新疆、内蒙古、西藏等祖国边陲，寻找在中原消失了一千多年的古籍、对话万里东归的土尔扈特后裔，探访神秘的“辫子坟”，探寻中华文明的强大凝聚力从何而来，又如何建立。

Traveling to the border regions of Xinjiang, Inner Mongolia, and Xizang, this episode examines how the unifying force of Chinese civilization has preserved diverse cultures and traditions across vast distances and centuries.
