傻子被骗子骗了很久骗子把傻子骗了很久
[shă zi bèi piàn zi piàn le hĕn jiŭ piàn zi bă shă zi piàn le hĕn jiŭ]
'A fool was deceived for a long time; the deceiver fooled him for such duration.' It humorously or sadly illustrates being gullible enough that one was tricked persistently and repeatedly for a prolonged period of time, highlighting naivety or perhaps regret.
