The villagers searched for underground work blocks

Villagers always regard my barrel and blast furnace as their work piece, this led the villagers always watch to the ground and try to attempt to break into my basement, not just like that, the villagers also try to take up my bed: / and now there are many fishermen in the village, and they never supplementary materials, or just try another work block what i already set in closer to them in the village,just on the ground, but they never do this

And i tried to break the barrel and put it back,this just work a little moment,now i have to use chest to instead barrels
