大器晚成 — “Great talents mature slowly”

Cui Yan, a retainer of Yuan Shao, initially had a strong interest in martial arts and only began studying classics like the Analects and Han Shi at the age of 23, seeking teachers for his studies. Through diligent effort, his knowledge steadily grew.

At that time, Yuan Shao's soldiers were notoriously brutal, even digging up graves and exposing corpses. Cui Yan advised Yuan Shao against such actions, and Yuan Shao, acknowledging the wisdom of his words, appointed him as a cavalry commandant.

Later, Cui Yan followed Cao Cao and offered numerous strategic insights. While serving as Minister, Cao Cao considered making Cao Zhi his successor, but Cui Yan objected, stating, 'The tradition from ancient times is to establish the eldest son; how can Cao Zhi be chosen?' Even though Cao Zhi was Cui Yan's niece's husband, Cui Yan showed no partiality, and Cao Cao greatly admired his fairness.

Cui Yan had a cousin named Cui Lin, who in his youth had neither achievements nor reputation, and was often looked down upon by relatives and friends. However, Cui Yan held him in high regard, often telling others, 'Individuals with great abilities require a long time to fully develop; Cui Lin will certainly achieve great things in the future.' Later, Cui Lin indeed rose to prominence, becoming Secretary of Yizhou, then Censor-in-chief, and even served as Minister of Works under Emperor Wen of Wei.
