请出示护照。
Show your passport
This is a polite command: qǐng (please) + chūshì (show/produce) + hùzhào (passport). 'Chūshì' is a formal verb for presenting documents.
You'll hear this from immigration officers. It's a polite but firm instruction. As a traveler, you might respond 'hǎo' (okay) and hand over your passport. Don't use this phrase yourself unless you're in an official role.
“Show your passport” in Chinese is 请出示护照。 (qǐng chūshì hùzhào).
请出示护照。 is pronounced qǐng chūshì hùzhào.
