What kind of poem is the ancient poem "Far Altair"?

The whole poem of "The Far-Away Altair" is: Far-Away Altair, a Han woman in the Jiaojiao River. The slender hands are used to make tricks. I can't make up my mind all day long, and my tears are like rain. The river is clear and shallow, only a few degrees apart. There is a room full of water, and the pulse is speechless.

The meaning of this poem is: Altair is visible far away in the southeast of the Milky Way, and Vega is bright and clear in the west of the Milky Way. The Weaver Girl was waving her long, white hands, and the loom was making a steady sound. I didn't weave a piece of cloth all day long, and my tears fell like rain. The Milky Way looks clear and shallow. How far is it between the two banks? Although they were only separated by a Milky Way, they could only look at each other lovingly and speechlessly.

This poem uses the tragedy of the myth and legend that the Cowherd and the Weaver Girl were blocked by the Milky Way and could not meet to express the woman's longing for parting.
