曹叡
In 236, Sima Yi caught a white deer, which was regarded as an auspicious animal, and presented it to the Wei emperor, Cao Rui. Cao Rui said: "When the Duke of Zhou assisted King Cheng in governance, he presented white pheasants to the king. Now you are in charge of Shaanxi and you present a white deer. Isn't this a sign of loyalty, cooperation, long-lasting stability, and peace?" Later, when Cao Rui asked for capable and virtuous men to be recommended to him, Sima Yi chose to recommend Wang Chang.
