Which songs of Jay Chou contain little-known mysteries?

In fact, when I was listening to Jay Chou's songs, I was attracted by the beautiful music, because most of us didn't know what Jay Chou was singing. But later I heard that when he sang this song "You Can Hear", some of the lyrics were sung backwards in the middle. Although we don't study music, we don't know what these represent, but Jay Chou may have his intention in doing so.

Another song was discovered by musicians, that is, Jay Chou's five mistakes and eight beats in the song "Piano Injury" will make the music sound like a wonderful double-opening effect, especially when listening to it in stereo, which is very obvious. Although we don't have the ears of music, the resolution may be much worse, but as long as you listen to it a few times, you will feel its beauty. So Jay Chou's songs were incomprehensible at first. Listen to it a few times, or understand it carefully, and you will understand.

Another netizen said that the lyrics of Jay Chou's Sunny Days didn't end until the end, and the meaning was not realized until the expression failed. The last sentence? You told the last story, and at the end, you said goodbye? That's the word. He just doesn't understand why he uses bye-bye instead of goodbye. Since he was in After Lovelorn, he realized the meaning, because people always smile when they are lovelorn, as if they will not be disturbed by lovelorn, so the word bye-bye will be squeezed out of their mouths.

And all young people will say goodbye when they are lovelorn, not goodbye. So he didn't understand until that day that Jay Chou meant bye-bye. At the end of the song, which is also the lyrics of this cycle, the word bye-bye was removed from the last sentence, so he recalled that after he said goodbye, the girl turned away without even saying goodbye to him, and he also sighed.
