Hi,
What does it mean "pass through"?
Thanks.

I suspect you're not a native English speaker. What is your native language? I may be able to translate or point you to website that can.

In general terms, it means to move in something and out the other side. It also means to visit somewhere briefly.

Thank you for your help.
Yes, I'm not a native English speaker. I'm Vietnamese.
However, your explanation is satisfactory. Thanks.
