This is an ancient poem praising maternal love. The original poem is a thread in the hands of a kind-hearted mother.
Sewing clothes for her traveling son.
She sewed carefully and repaired it thoroughly.
Afraid of the delay that will make him go home late.
Grateful to the humble grass
Did you repay the kindness of generous Sun?
Especially the last two sentences. It means that children are like grass, how can they repay the great maternal love like spring?
