Why does Zhuge Liang like to sing Song of Fu Liang?

Because this song "Song of Father Liang" is an inspiring song of counselors, it is entirely possible for Zhuge Liang, as a passionate young man determined to rejuvenate the country, to write such a poem. However, before Zhuge Liang wrote this song, there must have been several songs about Fu Liang. Because of such a vivid and touching story, although the local folk songs could not be sung, they were not as well written as Zhuge Liang, or as hard as Zhuge Liang's brand, and finally did not spread to the world.
