If you don't believe me, there is a sentence in the greeting on the third page: "Thank you for writing so many good songs for me ..."
The most important thing is that there is such a sentence in the sixth picture: "And the word' fable' you wrote is really well filled ..."
It can be seen from these stories that "Tina" is Wang Yajun who wrote "fables" for Shao Han.
And every album in the future has Wang Yajun's lyrics. If you have all Angela's albums, you might as well turn them out and have a look. I have confirmed it ~ ~
