人在江湖飘怎能不挨刀
[rén zài jiāng hú piāo zĕn néng bù āi dāo]
This phrase comes from the context of living a risky lifestyle in Chinese martial art culture. 'People live in a turbulent society (often associated with triads in some cases), so they cannot avoid conflict, dangers, and challenges'. Essentially this saying conveys a feeling of inevitability or fatalism, meaning if one enters a dangerous world, they shouldn't be surprised when they get hurt.
