In the third year of Jinghan's reign in Great Liang, Jiang Ce, dressed in white, held the northern gate alone. He slew a thousand Turkic troops, erected a boundary marker beside the Bishui River, and was ennobled as the Prince of Zhenbei. In the fourth year of Jinghan, the Prince of Zhenbei's old wounds flared up. He took to his bed, never to rise again, and the realm mourned. Two years later, the Turks invaded south. The Prince of Zhenbei's consort was forced to marry a Turk and sent away to seal a peace pact. That day, snow and wind filled the sky, and plum blossoms burst forth on a thousand trees. That day, the Prince of Zhenbei's black hair turned white, and a hundred thousand troops crossed the Bishui!
From then on, after three layers of snow upon your robes, who in the realm could be worthy of wearing white but the Prince of Zhenbei?
