In a world with historical gaps, Lin Chen relied on the live broadcast system to travel through thousands of years: talking to the First Emperor to break through the fog of Qin history, discussing border defense strategies with the Han Dynasty, discussing the wisdom of governing the country with Tang Zong, and meeting key figures such as Song Zu and Ming Tai... He used historical materials to re-enact the memory of the past, and used scene projection to evoke the resonance of civilization. From the explosive live broadcast room to awakening the hometown sentiment of the global Chinese, every dialogue across time and space is a continuation of the roots of China.
