Who is the author of a good kind of flax that has no seed and does not return when it is just returned?

Jingchai's hair is rare in the world, but the cloth skirt is still a wedding dress, and there is no one to plant flax, so it's time to return. This is a plaintive song sung by a working woman who misses her husband who is guarding the border. The first two sentences are portraits of a poor woman. Her hair was unkempt and her clothes were worn out. "Cloth skirt is still a wedding dress", which not only shows women's poverty, but also shows their yearning for their husbands. The last two sentences are rich in semantics. It is a good season to plant sesame seeds, but no one is planting them; Why didn't you come back when it was time to go home? There are worries that the farming season can't be delayed and the season can't be missed, and there are also sighs that youth can't be delayed, beauty is easy to get old and life time is short. The poet uses flax as an analogy to implicitly express the innocent affection of a boudoir who misses her husband. The whole poem is based on "Huai", which is also the difference between this poem and many poems about dissatisfied women.
