Respected General Secretary Kim Jong Un visited the Taedonggang Seafood Restaurant one day in June 2018. He satisfactorily looked at the shoals of fish swimming in an indoor pond before walking towards an angling site section. Then he suddenly stopped to carefully look down at the floor. Referring to the fact that the surrounding floors of the indoor ponds were covered with tiles, he said that the paving blocks for the interior should be laid slantingly for good drainage at such places as they might be slippery because of water dropping during service activities. In fact, he had taken every opportunity to stress the need to properly deal with the slant in construction. He had given detailed instructions as to it on his visits to the construction site of the Munsu Water Park and a factory. But the officials did not pay much attention to the slant because they thought the floors might get wet a little only when fishes are put into or taken out of the ponds. They were deeply moved by the world of warm love of the General Secretary who cares so much for the people lest they should have even the slightest inconvenience.
