背着棺材跳舞带着灵魂漫步
[bèi zhe guān cái tiào wŭ dài zhe líng hún màn bù]
'Dancing with a coffin while wandering with the soul'. This is an unusual expression combining dark humor with existential exploration, suggesting someone is living life fully despite (or even because of) the inevitability of death, indicating freedom and non-conformity.
