What is the poetic significance of the "bones of the Han and Wei styles" and the "style and elegance".

Liu Foxing and Zhong Rong were against the formalistic poetry of the Southern Dynasties, and they once cited the traditions of "Bixing" and "Style and Bone". Wang Bo opposed the court poetry style around Longshuo and also accused them of "exhausting the bones and spirit, and not hearing the robustness". Chen Zi'ang inherited their ideas and pinpointed that the Qi and Liang poetic styles, which were idolized by the court poets of the early Tang Dynasty, were "colorful and colorful, but all of them are extinct", pointing out the glorious traditions of "elegance and elegance" and "the bones of the Han and Wei dynasties" as the basis of the "style" tradition. He pointed out the glorious traditions of "style and elegance" and "style of Han and Wei" as the pioneering examples of creation, and realized the real innovation of poetry content under the banner of advocating the restoration of antiquity. The attitude is resolute, the banner is clear, and the call is powerful. Both "Xingmai" and "style" are the first and foremost issues related to the life of poetry. The essence of "Xingmai" is that poetry is required to carry forward the tradition of criticizing reality and to have a clear political inclination. The essence of "style" is that poetry should have noble and abundant thoughts and feelings, and robust and realistic content. In terms of the situation at that time, only by realizing the real innovation of the content can poetry take up the mission of the times.
