Si Jie is an outstanding figure in the early Tang literary world during the transition from the old to the new.
In terms of literary opinions, the four scholars strongly oppose the flashy style of writing and advocate expressing true feelings. Therefore, their criticism of Liang Wenfeng is particularly conscious.
Although the poems of the four masters have not lost their beauty since Qi Liang, they have initially reversed the literary atmosphere. Their poems have reversed the flagging and flashy atmosphere of court poems before the Tang Dynasty, expanded the theme of poems from pavilions and courtyards to the vast space of rivers, lakes and seas, and endowed them with new vitality. Lu and Luo's seven-character songs tend to be ci-fu, with a slightly stronger momentum; Wang and Yang's five-character rhythm began to be standardized, and the tone was sonorous. Parallel prose is also full of flexibility and vividness in ci.
The four masters made great contributions to ending the style of writing in Qi and Liang Dynasties and opening the voice of the prosperous Tang Dynasty.
