Colonize Nether in Minecraft PE?

I would like to build a city in the Nether, but you can't build fields for the villagers there. Do you have any tips on how to build a village there?

You can bend fields anyway, because you can't place water there unless you have mods (or in the case of Bedrock "addons") that allow this. Just take soul sand and these nether plants that you can find in the fortress, that should work, but I doubt that the villagers would take care of it. In other words, colonizing the Netherworld is a bad idea.

Can the villagers survive?

The nether plants are called nether warts and villagers do not need fields to survive.

You should just make sure that no mobs spawn that are hostile to the villagers and the villagers need work blocks (e.g. Brewing stand, composter…) and must not have access to beds because otherwise they will blow themselves up (beds explode in the Nether💥) .

Villagers are allowed to go to bed in the Nether

I think so. In safe areas from mobs like Wither Skeletons, Lohen and Ghasts, those in the Nether should also survive.

Oh uh yeah right🤦♂️
