sam1 zung1 jau5 sou3心中有數心中有数
Definition
To know exactly what is going on without having to say it explicitly; to have a clear idea or be fully aware.
How it's used
This expression carries a subtle, often cautionary tone, implying that the speaker is aware of the truth despite the other person's attempts to hide it. It is frequently used in confrontational or serious contexts to signal that further explanation is unnecessary because the outcome or reality is already understood. When paired with 啞仔食雲吞, it creates a classic Cantonese riddle where the punchline is 唔講大家知, emphasizing that the situation is understood without needing to be spoken aloud.

Common mistake
Do not mistake this for a literal calculation or math-related term. It is strictly used to describe a state of internal awareness or private judgment, not a numerical count.
