What does each sound file like a flower represent? The interval between youth I want to know why my Jinse has fifty strings.

"Jinse has fifty strings for no reason, one string and one column, which reminds me of the good times when I was young." According to the relevant information, I want to know why my Jinse has 50 strings, and each string has a flower-like interval. Jin Se, written by Li Shangyin in the Tang Dynasty, is the end of the poem, and the rhetoric progressive sentence pattern is used to strengthen the tone and end the whole poem. "This Feeling" summarizes the feelings expressed: "Memories of Time Past" and "The Year of Thinking of China" echo each other from a distance. "To be treated" means "to be treated", which shows that this melancholy and sad "feeling" has long been lost, and it is difficult to send it away, and it is even more unbearable at this time. Poetry creatively uses symbols and metaphors to develop the traditional "metaphor" method.
