The first sentence: abstinence from alcohol is actually a manifestation of Yu Shinan's noble life interest. Clear dew refers to morning dew, which is very clean and pure. Cicada only drinks such pure dew. Therefore, Yu Shinan is also expressing his lofty interest in life, doing what he wants to do, writing poetry, playing chess, painting and calligraphy, instead of competing with others and doing what he wants to do. There is a second sentence: the traffic sounds sparse. Here we see a word: paulownia, in fact, this paulownia is a phoenix tree. This cicada only lives on the buttonwood tree, and the buttonwood tree itself has noble attributes, from which we can see how noble the author is.
There are two last sentences: keep your voice high and don't be blown by the autumn wind. These two sentences are the true spirit of this poem. Literally, because the cicada itself is in a high position on the plane tree, the cicada in that position can spread far by itself without the help of autumn wind or anything else. So this also means that Yu Shinan himself is a noble gentleman. If he wants to be famous, he doesn't need to go along with those corrupt officials. He has strong ability and positive moral character, so he will naturally become famous.
Therefore, Yu Shinan's "Cicada" actually uses cicadas to express his inner thoughts and express his integrity. He doesn't need to go along with those corrupt officials. He will be a household name because of himself, so he will spread all over the world with his "Cicada" and be sung by us to this day.
