Beiyang, from the end of the Qing Dynasty to the beginning of the Republic of China, was an extremely short period of turmoil, a place where history turned, between the collapse of China's royal power and the upholding of civil rights, at the top of all human desires, a group of martial soldiers, a group of shrewd politicians, and a group of darlings of the times. What emotions, intelligence and cost did they use to perform the ending drama of a thousand-year feudal history? Beiyang, how should we look back at it? Hiding history and thinking about it, perhaps we can only sigh!
