Is there any meaning or hint of Zi Xue's evil deeds?

Xue Yuan is a kind of Artemisia, whose side branches are evil, that is, the son of this plant is evil, and "evil" comes from this.

E Lai was used to describe illegitimate children in ancient times. Because of their inferior position, there are always various struggles between illegitimate children and their sons. Over time, evil children have been used to describe those children who are unfilial and misbehave. Sin has its present meaning.
