As for "Literature" among the Six Arts, it simply meant to study. Reading brings wisdom, so the descendants of the Leng Family were required to read widely. They didn't need to master subjects like astronomy and geography, but they had to possess a general understanding.
Only by reading enough and gaining a deeper understanding of the world could one learn to handle matters with composure and face the complexities of human nature with greater equanimity.
It was thanks to this wisdom from books that when his grandmother came to cause trouble, Leng Yuan had decisively traded their family courtyard for a formal letter severing their ties, thus avoiding future complications.
