What does it mean that the most unforgettable but disdainful ancient poem is acacia?

The song "Acacia" sung by Mao Yamin means this: What I want to forget most is the person I miss most (but I can't), which reflects the profoundness of ancient poetry books and makes me infatuated with it.

The lyrics are as follows:

Red beans grow in southern China.

This is a very distant thing.

What is Acacia?

A long time ago, no one cared

Zuiwo sleepless city

Neons are everywhere.

The wine glass is very amorous.

Most willing to forget ancient poetry

The most dismissive thing is acacia.

Keep loving and be afraid of others laughing.

Still afraid of being seen clearly

Spring has come to see the red beans in bloom again.

I don't see a lover picking it.

Fireworks carry romantic feelings.

Most willing to forget ancient poetry

The most dismissive thing is acacia.

Keep loving and be afraid of others laughing.

Still afraid of being seen clearly

Spring has come to see the red beans in bloom again.

I don't see a lover picking it.

Fireworks carry romantic feelings.

Extended data

The whole song expresses "Acacia" around the title of the song, a kind of advanced and delicate emotion.

This feeling of lovesickness makes people crazy, and they are afraid that others will see it clearly and that they will be laughed at. This kind of pain can only be buried in the heart, and lovers can never express it. Acacia to the deepest, but show disdain.

The lyricist used two "most" words in the lyrics to emphasize the tone, which is actually a kind of irony, which just shows that lovesickness is the most unforgettable. She is not so much talking about what she is exploring as expressing her feelings, and more like lamenting her life.
