Pomegranate, the city flower of Xi'an, was introduced to China from Iran during the Han Dynasty. Based on the pomegranate, this documentary shows a deep reflection on the intrinsic connection between the two cities of Xi'an, China and Isfahan, Iran, through the perspectives of an Iranian professor of history and a Chinese documentary filmmaker. At the intersection of tradition and modernity, it links the historical heritage and spiritual commonalities between China and Iran, and deepens the understanding of the history and modernity of the two cities from a new perspective.
