In fact, this is a question that has been discussed countless times by countless people.
First of all, in the era when money and interests are the most important, who will work hard for unprofitable things? Besides, although Chinese characters are widely used, they have reached the limit after several generations of poets' application. The scenery is still those scenery, the sun and the moon remain the same, the four seasons bloom, the human customs have changed, but they are similar. Besides, poetry is slightly similar to others, which is called plagiarism, and all kinds of abuse and critical comments are even more useful.
In addition, the same is true of ancient poems such as sketches and cross talks. Once they get to the screen, it's hard to break through.
Classical poetry is highly generalized in ideological content, fantastic in conception, concise in writing and flexible in rhetoric. With beautiful artistic conception, heroic style and romantic techniques, it forms beautiful scenes to express the poet's thoughts and feelings. This requires a poet to have a solid language foundation, profound literary accomplishment and rich life experience in order to write a relatively high level of ancient poetry. Compared with modern poetry, it is much more difficult.
One more thing, the times are not proud of poetry and songs. Even if modern people create a few good poems, they will not be respected compared with those famous ancient poems.
Because now people pay attention to reality and practical education, but not to flashy ancient poetry. Besides, writing good ancient poems is gifted, which is not something that ordinary people can learn. This is also a threshold for some highly educated people. In this era of developed internet, perhaps an uneducated ordinary person can publish a blockbuster poem on Baidu, which can only make those celebrities afraid to publish their own works, indirectly affecting their enthusiasm for supporting the creation of ancient poetry.
