Zhang Fei is Liu Bei's sworn brother in the Liu Bei Group, and he is also very loyal to Liu Bei. Zhang Fei is also a valiant soldier. No matter how ugly Zhang Fei's image is in The Romance of Three Kingdoms, one thing is certain: Zhang Fei is a tall man, but in The Romance of Three Kingdoms, Zhang Fei's dark skin and beard make people feel ugly, but it is also possible that Zhang Fei, who has lived in the army all the year round, has been tanned a little. Therefore, it is normal to have a full face of beard, so it is very likely that the image of Zhang Fei seen in Romance of the Three Kingdoms is his unkempt appearance when he went out to war, which will naturally look ugly.
In fact, Zhang Fei respects literati very much. He is different from Guan Yu. Guan Yu looked down on such a sour scholar. He pays more attention to his soldiers, but Zhang Fei respects literati very much. Therefore, it can be seen that Zhang Fei should be a man with a certain culture, so he will respect literati. Plus, when he married Xiahou's daughter, although he saved this beautiful young lady by the roadside, if he is ugly and tacky, according to the Hou Shi family in the Three Kingdoms.
Later, Zhang Fei's daughter also married Liu Chan of Shu Han. Not to mention how beautiful Zhang Fei's daughter is, at least she is not an ugly person, so Zhang Fei will not be ugly, otherwise his daughter will really say whose child this is.
