First, read the English article below.

If something happens to your passport, or any important travel documents (like an identification card, any visa information, etc.) you want to have duplicates of those to show to police or to a consulate.  Keep your duplicates in a different place than your actual documents. For example, if you have a purse you're keeping all the important documents like passport and so on, keep your duplicates in a different bag. You should also leave duplicates of everything with a trusted friend or family member. That way if everything gets lost or stolen you can contact them and get the copies of the documents from them.

While you're probably not going to be able to become fluent, you should at least make sure you can access enough of the language to communicate if you get into trouble.  Have a sheet of important phrases (not just "Where's the bathroom?") with things like: how to get to the train/bus station, where is the nearest police station/home country consulate, internet cafe, and so on. Knowing enough to make basic communication with local people will make locals more likely to help you, because you have made an effort to be more than just a tourist. This is especially important if you're traveling alone. Somebody who is responsible should know where you are supposed to be and what you're supposed to be doing. This way, if you don't show up at the place you're supposed...
