The first reason is that Chen Youliang is headstrong, crony, narrow-minded, and does not allow others to have different voices, so he is suspicious of his subordinates. Chen Youliang lacks military leadership and strategic vision. Sitting in a land of plenty of food and clothing, short-sighted and not striving for progress. Missed the opportunity in the early stage, and was led by the nose and passively beaten in the later stage.
The second reason, it can be said that a person's success is really inseparable from the right time and place. Chen Youliang lost at the right time, and Chen Youliang used a serial ship, which can be said to be a shoo-in. Unfortunately, bad luck, the wind of decisive battle is wrong, Zhu Yuanzhang took the opportunity to burn the serial ship.
The third reason is that Xiang Yu and Chen Youliang are not in the same class at all. One is a general, one is a noble family, and the other is a weak scholar. One is outnumbered and the other is outnumbered. The same is that they are all children of Jiangdong, and their strategic vision is not long enough. Liu Bang and Xiang Yu fought for the world. When Zhu Yuanzhang and Chen Youliang fought, the Yuan Army was still there. This is not a nationwide conflict, but a war in Jiangsu Province.
The fourth reason is that Chen Youliang's life is not as bitter as Zhu Yuanzhang's. In the Poyang Lake water war, Chen Youliang's troops were stronger than Zhu Yuanzhang on the whole, and Zhu Yuanzhang was no different from the last fight. If he loses, he will be beyond redemption. On the battlefield, Zhu Yuanzhang himself was almost killed by the other side's capable general. As for Chen Youliang, it's unfortunate. As a coach, he was shot dead by an arrow on the spot. This is a small probability event, but when the commander-in-chief died, the morale of the army was in chaos and he lost to Zhu Yuanzhang.
The fifth reason is that the outcome of a war involves too many factors, and the number of troops is very important but not decisive. Chen Youliang didn't play cards according to common sense in the war, and his attitude was tough, suspicious and good at politics, which made it difficult for his generals to be loyal to him. In the key battle between Chen Youliang and Zhu Yuanzhang, Zhu Yuanzhang occupied a favorable geographical position, pondered the relationship between Chen Youliang and his advisers, prepared for the war in advance, and gave full play to the advantages of generals such as Chang Yuchun and Xu Da.
