Appreciate the following poem.

Appreciation: thorns, or vase flowers that are shy and boneless but can be pampered and show off their beauty; blood, or mellow and intoxicating wine that specializes in flattery. The praise and criticism here are self-evident. Ingenious metaphors are used to construct the framework of the whole poem. "Sigh" or "shooting" has clear emotions, "thorns" and "blood", and the images are accurate. At the moment of facing "suffering and truth", the realm of life is changed. now. The beauty of poetry's tension is fully revealed in this poem.

Lu Yuan wrote a poem "Poet" in 1949: "There are slave poets/He sings the secrets of suffering/He sighs with songs/His poems are thorns/Cannot be placed in a vase//There are Warrior poet/He sings the triumph of truth/He shoots with song/His poetry is blood/Cannot be poured into a chalice.” This could almost be an appropriate description of the poet's writing as a whole and his motto. This is a poet who has gone through many hardships and still pursues the true meaning of poetry. This is a poet who intervenes in history and has the will to seek truth. In a revolutionary era where the body and mind are being purged and "sublimated", one can imagine how difficult it is to be a poet, an excellent poet. In the history of contemporary Chinese new poetry, due to the repeated regulation of intellectuals by political movements, poets in this context either followed the times and sang carols and hymns; or they became silent due to suffering, or they continued to sing because they had endured purgatory. The poet Lu Yuan undoubtedly belongs to the latter. When Lu Yuan entered a new era with full of hope, his "happy flame" and the singing that resulted from it endured a long period of hardship after a short period of time.

It has become the fate of a poet to fight against suffering and use poetry to sincerely record the hidden worries and inexplicable spiritual history of the next generation. It was in this era, on the cliff of suffering, that Luyuan used his noble personality and melancholy singing to complete the transition between "tightrope" and "blade" during the difficult trek. In countless dark nights, the poet chewed the pain and chanted the lines of tears and blood.
