"Don't wait to push yourself" means that ambitious people will consciously move towards their goals without external pressure. This is a poem written by the poet when he was over the age of ancient times. With the help of the image of an old ox who is tireless, vigorous and self-reliant, he praised the working people's lofty aspirations of "being old, being ambitious and heroic in their twilight years".
Li shangyin
Li Shangyin (about 8 13 ~ 858), a native of western Henan, was born in Hanoi, Huaizhou (now Qinyang City, Henan Province). A famous poet in the late Tang Dynasty, together with Du Mu, was called "Little Du Li". In the second year of Kaicheng (837), he became a scholar, became a secretary of provincial studies, and moved to hongnong county, becoming the staff of Wang Maoyuan (father-in-law), the messenger of Jingyuan era. He was involved in the political whirlpool of "the dispute between Niu and Li" and suffered exclusion and frustration all his life.
Li Shangyin was one of the few poets who deliberately pursued the beauty of poetry in the late Tang Dynasty and even the whole Tang Dynasty. He is good at poetry writing, and parallel prose has high literary value. His poems are novel in conception and beautiful in style, especially some love poems and untitled poems are touching, beautiful and moving, and are widely read. But some poems (represented by Jinse) are too obscure and confusing to solve.
