Answer 1: The authorities are in the dark, the onlookers are clear. What's more, we comment on history to say what has happened, is to analyze in the known situation, thinking, everything is the result of deep thought. At that time in the bureau of the people are faced with the unknown robbery, the king loses, losing is not only the problem of the loss of the kingdom, there are hundreds of thousands of lives, and even their own head. People because of the unknown and fear, because of fear and inevitably have omissions. In addition, there are personal factors, Chen Youliang is just ruthless, has been practicing the thick black science, deep confidence that ruthless enough, hand hot enough to get everything, while his opponent Zhu Yuanzhang is skillful in strategy, well versed in the art of war, and more importantly, he is almost not due to the majority of the people get the opinion of the people to easily doubt their own views.

History is because it is unpredictable and unexpected, we have unlimited interest in it, your opinion is that you read the book when you come to your own, it is very good, but it is only a "horse hindsight", huh, keep this attitude to read the book is good, as for some things to get to the bottom of the matter I personally believe that there is no use! I don't think it's useful to get to the bottom of some things, because those things are already there.

Answer 2: Sun Tzu's Art of War says: "The upper army is the most powerful, the upper army is the most powerful, the lower army is the most powerful, the lower army is the most powerful, the lower army is the most powerful, the lower army is the most powerful, and the lower army is the most powerful. Posterity has been for Chen Youlang this decision is not understandable, why not directly attack Yingtian it, then Zhu Yuanzhang will be surrounded by enemies, unbearable, Chen Youlang why ready-made cheap not pick it

This seems to be a very difficult to explain the problem, but I believe that, in the Chen Youlang, the problem is very good to explain.

Chen Youliang's weakness of character destined him to attack Hongdu. He is a man with a black heart, who has always lived in betrayal and deception, and is no stranger to these things, and Hongdu's defection should not have been anything unexpected to him. But psychologically speaking, the most taboo thing for a person like him is to be betrayed by someone, and for a person, what he detests most is often what he is good at. What belongs to me, I must get it back! If I capture Hongdu, I will be able to teach those who betrayed me a lesson, so that they will understand that they must be absolutely loyal to me, Chen Youliang! Only allowing me to lose the world, not allowing the world to lose me, is a common problem of these people. Of course, there are many benefits of taking Hongdu, this place can be used as a base for attacking Yingtian, can be attacked, can be defended, if the attack is unfavorable, can also control the downstream, and Xu Tu to fight again. The various anecdotes of the playboy Zhu Wenzheng naturally reached Chen Youliang's ears. This was another great encouragement to him. Taking down Hongdu is as easy as a slap in the face!
