In political struggles and wars, it is common to leave a backward path. At best, it is moderation, caution and improvisation. At worst, it is indecisive, soft-hearted and weak-willed! Because many times you have to be resolute and decisive, and you will be born when you die! There are many examples in ancient and modern China and abroad. Cutting the grass and getting rid of the roots are all of this type, and the policy of appeasement and Huairou also belongs to this category. In fact, the so-called traitors are also of this type. He wanted to stay behind, but unfortunately he blocked the road ahead. Some smart people sneak in and please both sides, thinking that the front and rear roads are connected, but in fact they are blocked! In fact, this is especially true for leading generals. Taking the lead in joining the army is becoming more and more brave. On the contrary, like Mr. Jiang, he arranged the posterior road early. Although it is also a failure to arrange the posterior route, it is not the issue discussed here. Anyway, he also lost his way out!
