In fact, it is not impossible for Woods Valley to have whimsical plans, but Zhuge Liang vetoed Wei Yan's Woods Valley. Some people say that Zhuge Liang was afraid that Wei Yan's outstanding military exploits would threaten his position, so he vetoed the coup in Woods Valley. Others say that Zhuge Liang is too cautious to give up the ingenuity of Woods Valley. For thousands of years, historians have been discussing why Zhuge Liang rejected the whimsical plan of Meridian Valley, whether he dared not try it or whether there were other reasons.
First of all, Ziwu Valley Road is about 330 kilometers long from north to south. Because of the Qinling Mountains, the road is more dangerous. Tens of thousands of troops can't get through, but teams can still get through. If it is quietly led a good soldier, follow the example of Han Xin's Ming Xiu plank road and sneak into Chang 'an. At this time, Zhuge Liang passed by with a great army. After the camp, the soldiers pointed to Luoyang, and it was not impossible to pacify the world. There are three reasons why Zhuge Liang vetoed the whimsy of Weiyan Meridian Valley, and we will break them down one by one.
First of all, is Zhuge Liang's goal really Chang 'an? At that time, Shu Han could protect himself, but if the northern expedition was carried out on a large scale, the transportation of grain and grass would become a big problem. The failure of Zhuge Liang's Northern Expedition was mostly due to lack of food and grass, and eventually failed. Think about it from another angle. Zhuge Liang occupied Liangzhou and other places all the way to the northern expedition, stabilized the rear, gradually eroded the Central Plains, and looked for opportunities to recover the Central Plains in the war. This is not impossible, but it is different from Zhuge Liang's slogan of the Northern Expedition.
Secondly, there are difficulties. Meridian Valley is a path. If Wei Jun is stationed in Taniguchi with a small number of troops, Chang 'an will be prepared, even if it cannot wipe out Wei Yan's 5,000 chosen men. At that time, Wei has no way out, either capturing Chang 'an or dying at the gates of Chang 'an. Thousands of years later, at the end of the Ming Dynasty, Gao Yingxiang crossed the Meridian Valley. As a result, Sun Chuanting held Taniguchi and annihilated the rebels in Gao Yingxiang. Combined with the first article, in view of the high risk of Woods Valley Wonder and the fact that Chang 'an is not the primary goal, there is no need to implement Woods Valley Wonder.
The most important one:? The military aircraft incident cannot be discussed in court. ? At that time, Wei Yan put forward the mysterious plan of Meridian Valley in front of many people. Although feasible, it will never be implemented. There are countless failed actions because of spies in history. There were so many people at that time that it was impossible not to be known to Wei. If Wei learns these details, he will die. Later, Zhuge Liang also said to Wei Yan: March should be kept secret. If you have any whimsy in the future, you can talk to Liang privately and don't argue in front of the account. If there is a detailed report, Wen Chang will die. ?
First of all, the main goal is not necessarily Chang 'an. Secondly, this behavior itself should be kept secret. However, Wei Yan put forward this ingenious plan before the military account. The risk factor is extremely high and the leak is serious. Of course, the ingenious plan of Woods Valley is not feasible.
