Why did ancient Chinese poetry mature early and novels mature late?

In ancient China, poetry matured early while novels matured late. The main reason was that ancient novels and poetry were created in different ways. The creation of poetry was mainly carried out through oral tradition and literary inheritance. The creators of poetry were usually poets or poetry lovers who created according to their own preferences and creative inspiration. Because the artistic form of poetry was relatively fixed and the difficulty of creation was relatively low, poetry was quickly widely spread and accepted in ancient society. In contrast, the creation of novels is mainly through written culture. Its creators are usually novelists or literary critics. They need to conduct in-depth research and analysis of history, society, human nature and other aspects in order to create excellent novels. Because the difficulty of writing novels was relatively high, novels were a late bloomer in ancient society. The early maturity of poetry and the late maturity of novels were mainly due to the different ways of writing ancient novels and poems.
