Extended information

1. Creation background: Du Fu moved to Kuizhou in the summer of the first year of Dali of Emperor Daizong of the Tang Dynasty (766). There is the Wuhou Temple in Kuizhou and the Eight Formations on the riverside. It is said that it was built by Zhuge Liang on the river beach of Kuizhou during the Three Kingdoms period. Du Fu, who had always admired Zhuge Liang, used a lot of pen and ink to express his feelings by praising historical sites. "Eight Formations" is one of them.

2. Two sentences praising Zhuge Liang’s great achievements: “His achievements cover three parts of the country, and he is known as the Eight Formations”. Zhuge Liang made the most outstanding achievements in the process of establishing the situation where Wei, Shu and Wu were divided into three parts of the world. The creation of the Eight Formations made his reputation even more outstanding. In the three or four sentences, Liu Bei made a mistake in swallowing Wu, which destroyed Zhuge Liang's fundamental strategy of uniting Wu to fight against Cao, so that the great cause of unification died midway, which became an eternal regret.
