sinkhole
학생이 쓴 원문
I guess that many sinkholes relate to excessive construction or ignoring regulation construction.
There have already built big and high building, roads and and subway n the Seoul .
It is natural that the ground is weak.
We should refrain from big and deep construction in the Seoul for our safe.
