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

The story behind the answer

Zhao Yun is correct because the Peach Garden Oath was sworn only by Liu Bei, Guan Yu, and Zhang Fei. In Romance of the Three Kingdoms, these three pledged brotherhood in a peach garden to restore the Han, vowing to live and die together. Zhao Yun joined Liu Bei later and became a stalwart Shu general, but he wasn’t part of that original oath.

Context and memory tip: The oath scene comes from Luo Guanzhong’s 14th‑century novel and symbolizes loyalty and righteousness. Remember it as the “Peach Garden Trio”—
