In 878 AD, the beacon fire of Huang Chao's uprising ignited the last embers of the prosperous Tang Dynasty; in 960 AD, Zhao Kuangyin wore a yellow robe at Chenqiaoyi, ushering in the 300-year foundation of the Song Dynasty. In this bloody rift that lasted less than a century, China experienced the most violent rotation of power, the most absurd game between kings and ministers, and the most tenacious survival of civilization - this was the forgotten rift era between the Tang and Song Dynasties, and it was also the scene of China's painful transformation from a medieval aristocratic society to a modern civilian society.
