自作孽就不可活做好事却不懂活
[zì zuò niè jiù bù kĕ huó zuò hăo shì què bù dŏng huó]
The saying translates as 'Self-inflicted wrongdoings can be unforgivable, but doing good does not guarantee a better life.' It reflects a complex view on morality and life's unfairness: even those who do the right things may struggle while self-destructive actions bring lasting consequences.
