如果感到幸福你就跺跺脚
[rú guŏ găn dào xìng fú nĭ jiù duò duò jiăo]
This is an interesting play on the common saying 'If you're happy and you know it, clap your hands.' Here it humorously substitutes clapping hands with stamping feet, adding a whimsical twist to expressing happiness or celebrating good fortune.
