I can often hear the children crying there, but I can't see them. There are two rumors: first, it used to be an orphanage, because many kids were born unexpectedly. Second, a child died in the elevator, which is right between the second and third floors.
So now employees often hear children crying at work. Later, they went to see Mr. Feng Shui, and people said what the reason was and how to solve it! That's the way!
