Facing the irreversible past, Cheng Xiaoshi wanted to change their future.
♬ Bird, you have to sing softly ♬
♬ أيها الطائر، غرد بلطف ♬
Die Vögel singen leise.
Pajarito, debes cantar suavemente.
El gorrión canta bien flojito…
Tout doux,
 tout doux le chant des oiseaux… 
Uccelli, cantate dolcemente
Pássaro, tem que cantar baixinho
