King Fu Jian of Former Qin and Duke of Yangping climbed to the top of Shoucheng city to gaze out. They saw that the Eastern Jin army's formations were in strict order and then looked again at the grass and trees on Mount Bagong. They believed that these were also Eastern Jin soldiers. Fu Jian turned and said to Fu Rong, "This is a powerful enemy, how can we say that he is weak!"
