Ziwei event

The ingenious planning of the meridian valley has been debated endlessly. Some people say that Wei Yan's meridian valley plan was not followed and missed the chance of success in the Northern Expedition. Some people say that Wei Yan's meridian valley plan is just an armchair strategist and does not conform to the actual situation. So, is the mysterious plan of Meridian Valley feasible in a specific historical period? Let's explain the success of Woods Valley and the reasons behind it.

Ziwu Valley is one of the six roads in Qinling Mountains, with steep terrain. Qinling Mountain leads to Guanzhong, which is the most difficult road to pass. During Zhuge Liang's three northern expeditions, Cao Zhen decided to attack Shu Hou from the Meridian Valley, regardless of opposition. When Cao Zhen led his army through the Meridian Valley, it suddenly rained heavily, the road was destroyed, and the soldiers had just been around for half a month. As a surprise attack, it took a long time, only to retreat. The raid ended in failure.

In 354 AD, Huan Wen's Northern Expedition was divided into two factions. Sima Xun is going to cross the Qinling Mountains from the Meridian Valley, outflanking from the rear, and the former Qin sent people to defend. Sima Xun was defeated in the meridian valley, and one person kept it, and ten thousand people could not do it; Gao Yingxiang in the late Ming Dynasty and Gao Yingxiang in Shaanxi were both places where people wandered freely. Chongzhen wanted to destroy the lily, but there was no practical way. Chu Zhuangwang wants to make a big plan and win Chang 'an. As a local, he knew the meridian valley like the back of his hand, and led an army to raid Chang 'an from the meridian valley. As a result, I was unlucky and caught in a rainstorm. The initial ten-day raid turned into a half-month March. As soon as I got out of the valley, I met the Ming army. Therefore, the generals of the Ming army were ready to defeat the invading army.

There is no good end to taking the meridian valley in history. If we analyze the situation put forward at that time and lead 5000 people to cross the river quickly to Chang 'an, we will abandon the city and flee, provided that Xia Houmao really escaped, and the Shu army has only 5000 people. Without foreign aid, can he quickly occupy the ancient city of Chang 'an? The walls of this city are so thick that it is not easy to tear them down. Cao Wei received news that the army might wipe out 5,000 Indiana Jones.

Zhuge Liang, who drives carefully, did not adopt this strategy.
