In the novel, Guan Yu was praised by later generations for defeating Wen Chou by cutting Hua Qiong and Yan Liang, but Guan Yu was the last one to fight with these three men.
For example, before Hua Xiong War, Hua Xiong competed with Zu Mao, Lao She and Pan Feng.
Before Yan Liang was beheaded, Yan Liang fought against Song Xian, Xu Wei and Huang Xu successively.
When Wen Chou was at war with Zhang Liao, Guan Yu suddenly came out.
In fact, these are all made up by Luo Guanzhong, aiming at highlighting the bravery and good fighting of the three men, thus reflecting Guan Yu's ability from the side. However, this technique has also been interpreted differently by some people, because these three men had fought with other military commanders many times before fighting Guan Yu, and their physical strength was high. Guan Yu took advantage of their fatigue and finally launched an attack. Yan Liang and Wen Chou, in particular, fought with Huang Xu for 20 rounds before confronting Guan Yu. The scene was quite fierce. After that, Guan Yu did have the suspicion of picking up cheap, so there was a saying that Guan Yu "made up the knife and grabbed the head." Although it is not widely circulated, it does make sense to think about it carefully, and it is also an alternative interpretation of the novel.
Moreover, due to the influence of Romance of the Three Kingdoms, China folks have always worshipped Guan Yu very much, but the so-called extremes meet, and Guan Yu's image among the people has been resented by some people because of its great difference from history. Especially in recent years, the education level is getting higher and higher, and more and more people can contact and study history books. The Romance of the Three Kingdoms and the official history have great differences in Guan Yu's personal achievements. Guan Yu's negative image is gradually rising, and Guan Yu's image of "mending the knife" is gradually rising.
