Lü Meng captured Guan Yu, why is the historical evaluation extremely low? There are several reasons for this:
As one of the representative figures of the Shu Han dynasty during the Three Kingdoms period, Guan Yu's loyalty and martial arts are widely recognized in history. As a general of Eastern Wu, Lü Meng reneged on the promise of the Sun-Liu alliance and took the opportunity to sneak up on his ally Guan Yu, which violated the values of loyalty and faith at that time, and thus caused people's dissatisfaction and disgust.
Lü Meng's actions set a bad precedent of using camouflage and deception to backstab allies. During the Three Kingdoms period, commerce and trade were very important, and the caravan in white was the generally recognized image of the caravan at that time. However, Lü Meng used the image of the white-clothed caravan, disguised as a merchant, and attacked Guan Yu. This behavior not only undermined people's trust in commercial trade at that time, but also brought great trouble and danger to the subsequent war and commercial activities.
Lü Meng's actions dealt a fatal blow to the commercial trade during the Three Kingdoms period. In order to prevent sneak attacks, merchants had to spend more time and energy to protect their goods and fleets, which made commercial activities more difficult and dangerous. Therefore, Lü Meng's behavior not only damaged the commercial interests of the Three Kingdoms period, but also brought a great negative impact on the later commercial development.
The reason why Lü Meng's capture of Guan Yu has a very low historical evaluation is because his actions violated the values of loyalty, faithfulness and commercial trade at that time, and had a great negative impact on the war and commercial activities during the Three Kingdoms period.
