Those who know me worry me, and those who don't know me tell me to do whatever I want! What is the explanation of this sentence?

This poem is from The Book of Songs, the earliest collection of poems in China, and it is called Su Parting in Feng Wang.

People who know my mood think I am disappointed; People who don't understand my mood think I have any requirements for staying here!

The whole poem "Su Bieli" is as follows:

He left the millet, he is the seedling of the millet. He walked in decadence, his center shaking. Those who know me make me worry, and those who don't know me make me want. Who is this?

He is Xiaomi's ear. He walked in decadence, intoxicated with the center. Those who know me make me worry, and those who don't know me make me want. Who is this?

If you are separated from me, you will be real. If you walk in a decadent way, your center will suffocate. People who know me will worry me, and people who don't know me will tell me what I want. Who is this?
