У Саньгуй
Wu Sangui survived not only by following Wang Pu, but by having a good retreat plan. When Hong Chengchou ordered the breakthrough, Wu Sangui went back to his camp and immediately discussed tactics with his generals. They decided to give up the small path and flee on the main road. As expected, the Qing army had only cut off the small path, while no more than 400 soldiers held the main road under Hong Taiji. Seeing Wu Sangui's fierce charge, Hong Taiji restrained his army from pursuing. Hong thought highly of Wu, and considered gaining his favor as the key to conquering the dynasty.
