半世迷离Devil半世烟尘Devil
[bàn shì mí lí devil bàn shì yān chén devil]
This expresses a half-life feeling bewildered and chaotic (Devil here used repetitively might emphasize these chaotic feelings) and another half covered in smoke and dust, possibly implying half of one's life spent in bewilderment and frustration, and the other half filled with trials or experiences marked by hardship.
