What was the real Zhao Yun in history like? I need historical records, not novels!

I personally think that the Romance of the Three Kingdoms is a novel that can't be completely trusted. There should be some exaggeration.
1. Did Zhao Yun really enter Cao Cao's camp during the Battle of Changban Hill? Or was he really that powerful? (Killed countless generals)
2. Could Zhao Yun's martial arts really rank second in the Three Kingdoms? (I don't think there's any objection to Lu Bu being the best in martial arts.)
3. Was Zhao Yun really an all-rounder? (Powerful in martial arts, strategy, military, economics, and politics)

Answer 1

According to historical records, Zhao Yun was a loyal, brave, and resourceful general.

Zhao Yun served Shu Han during the Three Kingdoms period and served as the general and prime minister of Shu Han. In the war, Zhao Yun led the army to victory many times with his outstanding military talent and brave spirit, making an important contribution to the establishment and stability of Shu Han.

Zhao Yun had participated in many important battles, the most famous of which was the Battle of Changban Slope with Cao Zhen, the general of Wei. Zhao Yun performed well in the battle. With his outstanding martial arts and resourcefulness, he successfully defeated Cao Zhen's army and protected Liu Bei's youngest son, Liu Chan. He won Liu Bei's trust and respect.

Zhao Yun was also highly praised by later generations for his loyalty and courage. After the fall of Shu Han, Zhao Yun did not miss power and wealth but chose to leave Chengdu to defend the border of Wei, showing his loyalty and sense of responsibility to the country and the people. As a result, Zhao Yun became one of the famous generals and cultural symbols in Chinese history.
