What genre is this poem about my brother's life? What's the name of its quartet?

My brother lives in Liu Zongyuan.

Personnel to return, the residual soul Gu Ying times frustrating; There are tears on both sides of Liujiang River, and my brother cries.

The treacherous party, because the party did not leave the capital, lived more than 6 thousand miles away; I left Baiyue desolate, gaunt and poor for the rest of my life.

Guiling malaria forest, black clouds hanging white; Welcome to the beautiful future of Dongting with spring scenery and water and sky.

Fang Wei depends on dreams, and acacia is willing to sleep on the pillow; Wandering in the dim light, the clouds seem to be real.

The genre is seven-character verse.

The quadruple joints are head joint, parallel joint, neck joint and tail joint.

The main feelings to be expressed in the whole poem are: the poet's grief and indignation in political life.
