How to say "I lost my wallet" in Chinese

The structure is: 我的钱包 (wǒ de qiánbāo) means "my wallet," 丢 (diū) means "to lose," and 了 (le) is a particle indicating a completed action. So it literally means "My wallet has been lost."

Use this in emergencies, such as reporting to police or hotel staff. It's direct and clear. To add urgency, you can say 我的钱包丢了，请帮帮我 (qǐng bāng bāng wǒ, "please help me"). Avoid using it in casual conversation unless you're actually in trouble.
