In order to find a village in Minecraft already in the finished world, the most reliable way is to make a map. Keep in mind that the village appears only if the option of generating structures was selected when creating the world. Otherwise, the village is considered meaningless.
In order to find a village, and just be able to better navigate in the already created world, you will need to create a map. For this you will need:
- Workbench.
- Compass (to make it, you need four iron ingots and one red stone dust).
- Paper, a lot of paper, minimum - 8 sheets (one sheet is obtained from three units of sugar cane).
Now you can proceed to the production of the card:

Kraft's card and look at what happened.

If there is no visible on the village map, it will have to reduce the scale. We have a map on the workbench in the center, and we look at it with paper, as they did with the compass.

We look at the map, and if necessary, repeat item 3. If there is a village in this world, it can be seen on the map.

There are other ways to find a village, but they or are more time, or rather not suggest the search for the finished village, but its production at the stage of creating the gaming world.
