How to evaluate the lyrics of ancient songs?

Vincent Fang's recent Chinese-style Traveler at the End of the World for Jay Chou goes like this: The string is broken and you are gone. The story of love and hate ups and downs only left me a few times to leave this world and understand it. I asked if you were absent. Many words, such as the world and sadness, seem to see that numbness can't echo feelings. I'm not saying that Fang Gang's quality has declined. On the contrary, after years of experience and polishing, his Chinese lyrics have reached a very stable level. However, personally, I didn't feel that amazing at first. Another example is the famous sentence in Lu Xun's Autumn Night: In my backyard, you can see two trees outside the wall, one is jujube and the other is jujube. Do you feel anything? A seemingly nonsense sentence, read carefully, suddenly makes you feel helpless and at a loss. We all know that too much is not enough, but many times it is difficult for us to grasp the degree of too much and too much. But first of all, I want to say, how to judge the accomplishment of this word? Different people have different opinions. I only represent my personal opinion-I personally feel that just quoting a lot of old sayings can't promote ancient customs. A lyric may remind you of the past, may make you feel the same in an instant, and may touch a sudden sensitive nerve. This is the success of the lyrics. For grandstanding, it will make people feel embarrassed. I just feel that a bunch of allusions and quotations from poems have lost the aura and emotional expression of what I want to express, which makes people feel deliberate and artificial, and has not caused me much. Maybe I'm in a bad mood at the moment, and I can't feel what it wants to express. But I don't deny that its rhymes are exquisite, and the writer can't write without a certain accumulation of poems. However, emotionally, I didn't feel the emotion that most lyrics should have. Light has content, just as a man without soul is a robot. Are robots strong? Of course it's amazing, but it's not human at all. However, none of the above is useful. Everyone is different. As long as it touches you at a certain moment, it realizes its value. No matter how successful I am, what I like is good, no matter what others say.
