What slogan did the police school put forward in their creation?

The slogan put forward by the police school in its creation is "express your own spirit and not stick to one pattern". This is to require literature to fully express the author's personality and oppose the various rules and regulations set by the retro school in literary expression methods. They believe that "what comes from the soul is true poetry", and good poetry and prose are "willful" and "one piece flows out of the chest". This literary proposition played a positive role in "rejuvenation" and "anti-Taoism" at that time. They advocate writing in an approachable literary language, without using any allusions, and adopt a large number of proverbs, "It is better to be in front of people, not to be vulgar, and refuse to accept words". In this respect, they think they have accepted the traditions of Yuan Zhen and Bai Juyi. Their efforts made great contributions to the liberation of literary style at that time, and the poems of the public security school were once all the rage and became the objects of imitation and learning.
