Appreciation of a short lyric;

The theme of this "short song" is very clear, that is, the author is thirsty for talents and hopes that all talents will come to him.

In his political activities, in order to expand his ruling base among civilian landlords and crack down on reactionary hereditary forces, Cao Cao once strongly emphasized that "meritocracy means promotion", and for this reason, he successively issued orders to seek talents, promote scholars and escape.

In fact, "short song" is a "song of seeking the virtuous", and it is precisely because it uses the form of poetry and contains rich lyrical elements that it can play a unique infectious role, effectively publicize his persistence and cooperate with his decrees.
