I lost something while traveling, but I have already arrived in a different place. What should I do?

If you don't know what you have lost until you arrive in a foreign land, then see if all the lost things are valuable and meaningful. If you are far away from home and don't meet good friends at local tourist attractions, I'm afraid you will find a needle in a haystack. If the lost thing is more important, you can choose to call the police or go back and have a look. It may be possible to return it to you if you meet a kind person. If you remember where you put it, for example, you can try to ask. It's lucky to have them mail it back directly for you. Give them a good comment and send them a banner. Even if you tip them, I guess they are willing to help you.
