勾勾手的承诺撇撇嘴的誓言
[gōu gōu shŏu de chéng nuò piĕ piĕ zuĭ de shì yán]
This translates to 'Hand-hooked promises and pouted lip vows.' Hooking little fingers is a gesture for promising in China while pouting and vowing represents earnest commitments expressed dramatically or childishly, highlighting innocence and sincerity.
