In Romance of the Three Kingdoms, who was not a member of the Peach Garden Oath?

Zhao Yun was not a member of the Peach Garden oath in the historical novel "Romance of the Three Kingdoms" mainly because he joined Liu Bei's forces later in his life. The Peach Garden oath was taken by Liu Bei, Guan Yu, and Zhang Fei, who swore brotherhood and loyalty to one another before embarking on their journey. Zhao Yun, although a renowned general and loyal to Liu Bei, did not participate in the oath as he joined Liu Bei's faction at a later stage, after the alliance between Liu Bei, Guan Yu, and Zhang Fei was already established.
