What's the difference between Li Qingzhao's ci and Liu Yong's ci?

Li Qingzhao works hard in poetry, can write and is better at ci. With the changes of life in the Northern Song Dynasty and the Southern Song Dynasty, his works showed different characteristics in the early and later periods. Li Qingzhao's early poems truly reflected her boudoir life, thoughts and feelings, and showed natural scenery and parting feelings. Such as "like a dream" two songs, lively and fresh, meaning beautiful. Du Nan's post-ci style is also very different from that of the previous period, turning into desolation and pain, expressing nostalgia and nostalgia when he was injured. Such as "Bodhisattva Man", "Die" and the slow word "Ode to Fishing Music", all have a strong yearning for the motherland. In her poems, she fully expressed her deep sadness in her lonely life. Such as "Wulingchun", "Slow Voice" and "Qingpingle". The pain of national subjugation is integrated with the personal miserable life, and the sadness and melancholy are rendered to the extreme. It can be said that this is an artistic summary of the suffering of the times and the unfortunate fate of individuals. Liu Yong not only changed and developed the singing style of Ci from the music system, but also changed the aesthetic connotation and taste of Ci from the creative direction, that is, changed "elegance" into "vulgarity" and deliberately expressed the secular emotions of citizens' life in popular language. Liu Yong's poems are sad and touching, but affectionate but not decadent. The artistic conception of word formation is refined and unconstrained.
