After Wang Yajun composed "Fable" and "Unguessable" for Angela Chang, she created a warm folk song tailored for Angela Chang in the album "Pandora" - " Invisible Wings". Wang Yajun was particularly moved by Angela Zhang's clear voice. One particularly cold night, she suddenly hummed a piece of music. She thought it was very suitable for Angela Zhang, so she started writing the song.

The reason why Wang Yajun came up with the word "invisible wings" is because she felt that Angela Chang looked like the heroine in Hayao Miyazaki's movie "Spirited Away". Before her debut, Angela Chang participated in singing competitions. They all ended in failure, but they still persevered. This spirit is actually very "hidden girl", which gave Wang Yajun creative inspiration. In addition, Wang Yajun himself is also a creator who has gone through many setbacks.
