楊奉
Yuan Shu was furious that Lü Bu reneged on his word, so he allied with Han Xian and Yang Feng, and sent his general Zhang Xun (張勳) to attack Lü Bu. Lü Bu asked Chen Gui, "Yuan Shu sends his forces to attack me because I followed your suggestion. What should I do now?" Chen Gui replied, "The alliance between Han Xian, Yang Feng and Yuan Shu is formed by a loose assembly of their forces. They have not decided on a common plan so they will not last long. They are like chickens tied up together and they cannot move in tandem. My son, Deng, has a plan to separate them."
