Then why were there many famous poets in ancient times, and how were their poems known to many people? This depends on the poet's propaganda, one is active propaganda and the other is passive propaganda. Active publicity means spending manpower or financial resources to spread the excellent works that you are proud of; Passive propaganda saves time and effort. As long as most people realize that this is a good poem, they will consciously read it to their relatives and friends, much faster than actively promoting it.
However, passive propaganda needs good literary talent. Those people with average literary talent will spread poems in a small area all their lives, and there is no chance to rush out at all. Therefore, it is better to promote poetry by yourself, but there are exceptions. For example, the author of a poem is a big official or even a prime minister. In such a prestigious position, others will think that a poem with 5 points is 8 points, not to mention the people who help you spread and appreciate your poem may not really feel good, just to cling to the relationship and please you.
Ancient poets often communicated with each other, and they felt that the communication between poets was conducive to their own level of progress. Therefore, reading poems from each other has become a good way of publicity, especially when it is a blockbuster at the party.
