say：Adults
are renovating the slabstone house; they erect the slabstone first, and
then restore the missing bits with new bits of slabstone. These larger
and stronger slabstones are the walls and pillars of the house, to keep
the house robust.

may be recycled.
say：The smaller slabstones are fixed along the bigger slabstone to reinforce
it.
say：After
