Its publication is due to the mutation of literary thoughts of the Liang Dynasty, from which ripe ideas of compiling can be seen. The feeling of love is obviously inhered in its motif of selected poems, indicating that the Liang scholars had a tendency toward parochialism and entertainment. Xu Ling, compiler of Yu Tai Xin Yong, has both good and ill reputation.It is not a coincidence that Yu Tai Xin Yong and Wen Xuan had simultaneous existence, but a necessity that both collections became representatives of two schools of literary community of the Liang Dynasty, namely, mutation and adaptation in their likeness of political ideas and aesthetic taste. This is also the artery of the Liang literature.In the history of poetry Yu Tai Xin Yong has produced a profound influence on a train of literary phenomena such as printing of its amplification, compiling of its continuations, appearance of its replication and so forth. All of these are worth giving more attention and explanation. Its enlarged edition block-printed in the Ming Dynasty has the same purport as the original one, makes up some deficiencies, adds some poets of especially Xiao Tong and Pei Ziye, leading to our rethinking of three schools of literary community in that dynasty. Amplification itself is a special way of acceptance that suggests the aesthetic taste of the middle and late Ming Dynasty scholars. Its two complete continuations that have handed down to today are Continued Yu Tai Xin Yong and Tangshi Yu Tai Xin Yong, displaying that selected poems in Yu Tai Xin Yong have close relationship with poems in the dynasties of Chen, North, Sui and Tang. The existing Yutai-formed poems were written separately in. the dynasties of Tang, Song, Yuan and Ming. These poets copied Yutai-formed poems in their own style and made it accepted by the people.Studies on Yu Tai Xin Yong have been on since its appearance, generally speaking, along the tendency from sensibility to rationalism. Researches of Yu Tai Xin Yong had a turn till Ji Yun, a poetic critic of the Qing dynasty, who represented the attitude of orthodox scholars toward literature of love. Ji Yun gave a careful study of Yu Tai Xin Yong in its proofreading, enjoyment, origination and circulation, and thus made effective contributions to its restoration as a work of literature.
