老衲已到犯浑的年龄
[lăo nà yĭ dào fàn hún de nián líng]
In Chinese culture, '老衲' (lao na) typically refers to a Buddhist monk, but here it's a humorous way to say 'I'm getting older and acting more irresponsibly.' The phrase reflects someone embracing mischief or foolish behavior due to age, in a somewhat self-deprecating tone.
