Li Yan
After the Wei attack stalled due to continuous rainfall, Li Yan was not permitted to go back to the east; instead, Zhuge Liang included Li Yan as a member of his cabinet, granting the latter access to the Imperial Chancellor's office to help prepare for future campaigns against Wei. Thus, Li Yan changed his name to "Li Ping", compromised on Zhuge Liang's war plan, and accepted the role of a logistic officer for Zhuge Liang's fourth northern expedition.
