Why is Shu Han often regarded as "orthodox" in the traditional Chinese view of history since ancient times?

The Three Kingdoms period saw the decline of the Han Dynasty, Liu Bei established the Shu Han regime in Shu, Cao Cao's son gained the throne through Emperor Xian's abdication and established the Cao Wei regime, and Sun Quan claimed the title of Emperor in Eastern Wu and established the Eastern Wu regime, their statuses appeared to be the same to people at the time, but the traditional Chinese view of history regarded Shu Han as orthodox, and the other two countries as not orthodox. So what caused Shu Han to become orthodox? The founder of the Shu Han regime was Liu Bei, who was a member of the Liu royal family. Shu Han was considered a continuation of the Han dynasty, and the novel Evolution of the Three Kingdoms had Shu Han as the orthodoxy, which influenced a lot of people, and after the Southern Song Dynasty Southern Song Dynasty, Shu Han was considered as the orthodoxy for the sake of the political necessity, and thus the traditional Chinese historical view of Shu Han was considered as the orthodoxy.

I. The emperor of Shu Han was Liu Bei, who was a member of the imperial family of the Han Dynasty and therefore considered orthodox.

The founding emperor of Shu Han was Liu Bei, who was recognized by the emperor as an imperial uncle after King Zhongshan Jing of the Han Dynasty, and he had been playing the banner of restoring the Han Dynasty because he was a member of the Han Dynasty's royal family by birth, and therefore Shu Han was also regarded as the continuation of the Han Dynasty, and the other two founders of the country had been subjects of the Han Dynasty and had no relationship with the royal family of the Liu surname, which led to the people recognizing that Shu Han was the orthodox one.

Second, the Romance of the Three Kingdoms is more popular, the main character in the book is Shu Han, leading people to recognize Shu Han as the orthodoxy.

The story of the Three Kingdoms can be familiar to everyone, the novel Romance of the Three Kingdoms can not be faulted, the novel inside the Shu Han regime established by Liu Bei for the orthodoxy, Cao Wei and the East Wu are scandalized by the author, as long as the other camps have different disparagement, the prevalence of the book so that people mistakenly believe that this is the history of the orthodoxy, leading to the people of the Shu Han is more sympathetic to the Shu Han is the orthodoxy.

Third, after the Southern Song Dynasty, for political needs, Shu Han as the orthodoxy continues to this day.

From the late Three Kingdoms to the Southern Song Dynasty before the time inside, the history books have been Cao Wei as orthodox, Shu Han's existence is not strong, and then the Southern Song Dynasty Confucian scholar Zhu Xi changed the view that Shu Han is orthodox, Shu Han in line with Confucianism, and from then on after the historians agree with the view of Chu Hsi, the later dynasties have been using the view of Chu Hsi, because it allows people to be loyal to the country and in line with the political needs!
