The difference between recalling the past and hurting yourself.

Looking back on the past, learning from a painful experience is the expression of poetry. It refers to satirizing the present through the description of the ancients, ancient events and historical sites, or looking back on the past, learning from a painful experience, or expressing some feelings. To understand this kind of poetry, we must first contact the relevant writing background and find out the author's writing intention; Secondly, we should correctly understand and use some allusions.

For example:

For example, Su Shi's "Niannujiao Chibi Nostalgia" must first understand that when the poet wrote this word, it was nearly half a year old, but it was not reused by the rulers. If you are empty, you can't serve your country. It's hard to pay. Secondly, it is necessary to understand the ancient things described in the ci, such as Zhou Yu's heroic posture, feather scarf and determined conductor, and then understand that the author's writing purpose is to reminisce about the past and hurt himself: to express his feelings of having accomplished nothing in his career for nearly half a century through Zhou Yu's youth.

Another example is Xin Qiji's "Looking Back at the Gubei Pavilion at the Mouth of Yongyu Le Jing", which needs to contact the background of the Southern Song Dynasty ruler Pian 'an Jiangnan to understand the meaning of allusions such as Liu Yilong, Sun Quan, Emperor Wu of Song and Lian Po. It not only shows the author's strong dissatisfaction with the ruler's failure to recover lost land, but also shows his indignation that the ruler does not attach importance to himself, which hurts both now and himself. Others, such as Li Bai's Visit to Vietnam and Liu Yuxi's Stone City, also belong to this kind of poetry.
