When I hear a poem, I find that there are often many different versions of it. Some versions would focus on a certain aspect, while others might have variations of different values. For example, when I hear a poem, I usually want to know its original story. Because we are usually attracted by the content of the poem and pay attention to the background and the values of the characters. But there are also some poems that can have many different versions, each version uniquely creating some different values. These versions might pay more attention to the psychological changes of the characters or pay more attention to the rhythm and ending of the poem. Therefore, every poem has its own unique style and values, which are all important to us.
