Formal:
* 现在停止 (xiànzài tíngzhǐ): This literally translates to "stop now". It's appropriate for situations where you need to be direct and authoritative.
* 请立刻停止 (qǐng lìkè tíngzhǐ): This means "please stop immediately". It's more polite than the first option.
Informal:
* 停一下 (tíng yīxià): This means "stop for a moment". It's a more casual way to ask someone to stop.
* 别再 (bié zài): This means "don't continue" and is used to tell someone to stop doing something they are already doing.
* 够了 (gòule): This means "enough" and can be used to tell someone to stop doing something.
Example:
* If you want a child to stop running around, you could say: 停一下！ (tíng yīxià!)
* If you are giving instructions to an employee, you could say: 现在停止工作 (xiànzài tíngzhǐ gōngzuò).
It's important to choose the right phrase based on the situation and your relationship with the person you are speaking to.
