The Winds of Jinling

Gu Jinghao and An Ran were childhood sweethearts (Gu Jinghao was ten, and An Ran was eight). Their families had been close for generations, and had arranged a marriage between the two children when they were young. But more than ten years later, Gu Jinghao and An Ran found themselves on opposite sides. Gu Jinghao was a member of the Chinese Communist Party working undercover in the Military Intelligence Bureau, while An Ran was an agent for the Bureau. From then on, they became enemies.
