On the morning of the September 18th Incident in 1931, the 16-year-old Jiang Yunbai, the second daughter of the Jiang family, turned over the newspaper that had been seized by her parents at the dinner table, and began her magnificent but silent life.
As a talented girl from a wealthy family, she used the pseudonym "White Crane" to hide in the deep sea under the pseudonym "White Crane". In Shanghai during the isolation period, in Chongqing in the flames of war, and in the Kuomintang-controlled areas on the eve of the civil war, she moved accurately among multiple identities like an ice knife walking on a sharp edge. Along the way, she met the flamboyant and enthusiastic military reunification agent Fu Changheng, met the kind-hearted comrade Pei Baiheng, and faced off against the sober and desperate opponent Shen Gucheng. She has experienced the fiercest love, the heaviest betrayal and the coldest loss, but she always chooses to stand on the side of faith again after being shaken.
Intention: Faith does not never waver, but every time it wavers, it chooses the same path again. This book aims to explore the resilience of individual lives under the grand narrative. Through Jiang Yunbai's life, it shows how women digest pain and bear fate in extreme circumstances, and deconstructs spy wars with a "cold warmth": true heroism is not a smooth road without cost, but knowing all the costs, still walking towards the pure ideal with eyes open.
