What is written in the first section of Shu Ting's poem "Ah, Mom"? What's the role?

The first section describes the scene in which my mother cut my hair and I pulled my mother's skirt tightly in my dream, expressing my mother's love and attachment to my mother and setting the emotional tone of the whole poem.

Because now I have lost my mother's protection, and no one loves me, sympathizes with me and protects me.

Standard answer.
