2. The first category is the main theme of Lu You's poems. This kind of works mainly consists of two themes. On the one hand, it shows the great ambition of sacrificing oneself to serve the country, restoring the Central Plains, and eager to make contributions. On the one hand, it shows the anguish of hard-to-pay ambition and the grief and indignation of being unable to serve the country. These two aspects are often intertwined. This kind of works has the outstanding characteristics of romanticism, which are as follows: first, the desire to restore the Central Plains is often expressed through the description of dreams. Second, we often don't give a static and detailed description of one thing, but pay attention to the catharsis of self-emotion. Third, how heroic the language is. These characteristics constitute the bold and romantic style of Lu You's poems, which is close to Li Bai, a poet in the Tang Dynasty, so Lu You is called "Little Li Bai". The second kind of poems mainly describe daily life and scenery, and often experience special meanings from ordinary scenes, so the writing is beautiful and thought-provoking.
