There are many ancient poems in China, some of which are based on dissatisfaction with reality and long-term love for mountains and rivers, and express their feelings by describing the natural scenery of rivers, lakes and seas. Writing poems is also one of their daily lives, and of course it is also the content of their imperial examinations. Usually the ancient poems we see have their own names and dynasties next to them. That's because it was measured by experts after translation. In ancient times, they were usually made of paper, and a poem was a piece of paper. So they usually put their own seals on the lower left corner or the upper right corner of the poem, and write their own names and the time when they wrote the poem. And many times they have their own fans, and their fans or themselves will collect their stories into a book and then urge them to become a book. So usually they will have a book of poems, which contains their own ancient poems and will not overlap with others, so they can prove to be their own patents. Many times, different dynasties have different times of their ancient poems, so the times and styles of their works are also different, so the differences in writing styles between dynasties and individuals are also different in their patents. Therefore, the poems written by the ancients generally wrote their own names under their own works, stamped with their own seals or collected into books, which proved to be their own patents. This is my opinion. Do you have any better suggestions? Let's discuss them in the comments below.
