What are the two schools of Song Ci? What are the representative writers and works?

Song ci is divided into bold and graceful schools.

Representative of the unrestrained school:

Su Shi's red wall poems, setting wind and rain, don't listen to the sound of leaves beating in the Woods, Jiangchengzi has lived and died for ten years, when will the moon be there, and Niannujiao Chibi misses the past.

Xin Qiji's Anyuan, ugly girl tree Boshan road middle wall, Jiangbodhisattva jujube mouth wall, Qingpingle villagers live.

Representative of elegance:

Li Qingzhao? A plum in autumn, fragrant lotus root, fragrant jade, like a dream, the rain last night, the sudden wind, like a dream, always remember the sunset in the Xiting, whispering and looking for it.

Liu Yong? Chilling in the rain circle, falling in love with flowers, leaning against dangerous buildings, youth travel, Chang 'an ancient road, Mayan and Wanghaichao, win in the southeast.
