Poetry criticism has modern significance! It is mainly manifested in that modern people inherit, learn and pass on the spiritual culture of ancient predecessors, and it is very meaningful to comment on poetry. Of course, when we comment, we should not only keep praising, but also have critical spirit.
The predecessors are ancient, and they have the right to blame the king. People do things to uphold justice, and academics can be discussed. Academics should be regardless of territory, regardless of praise or criticism, because hard work is the essence. If discussions are modest, wouldn't it be a hypocritical hypocrite? If you open up this group, you can write as you like, and your merits and demerits are judged, so you are hesitant, but you can still be bold and free. Just don't comment on politics or attack personal dignity. Poetry criticism is simply cultural communication, and it is good for us to learn culture in comments.
