瞒着所有人怎么说英语

瞒着所有人怎么说英语 (mán zhe suǒ yǒu rén zěn me shuō yīng yǔ) means "How to speak English without letting anyone know" in Chinese. In English, a possible way to say this could be "How to speak English secretly". It is important to note that it is not always appropriate or ethical to keep secrets, especially if it involves deceiving others. It is always best to be honest and transparent in communication.
