This book uses characters as needles and history as threads to weave a picture of the rise and fall of the Qing Dynasty over three hundred years. From the dragon robes and phoenix crowns in the Forbidden City to the fireworks in the alleys, with textual research as the backbone and literature as the wings, the dusk and rebirth of the feudal dynasty is outlined in the ups and downs of the emperors, generals, ministers and strange people in the city. A glimmer of humanity can be seen in the deep sea of history, and the group portraits depict the codes of the Sino-Tibetan era. It is a biography that makes history tangible and tangible.
