Since the selection of Wei in the Book of Songs is about war, why choose Wei as the topic?

The title of The Book of Songs is usually selected from the first sentence. The first sentence of picking EU:

"Take the EU and take the EU, and the EU will not."

So I chose to choose the EU as the theme.

"Xing" is widely used in The Book of Songs, so there are many poems that usually describe daily work scenes at the beginning.

For example: picking midges, plums, kudzu roots and so on.
