Feng Shui is a complete system ... You can't go to see it just because of one thing. For a simple example, your ears may not be very good, but other five senses are beautiful and handsome if they look good. What's more, kindergartens are not places where evil spirits are heavy. Generally speaking, they have little influence.
It really depends on the feng shui of a room, the overall external pattern, the internal room setting and the furniture layout.
Of course, aside from geomantic mathematics, we can know from common sense that there will be noise in kindergartens, which is also a kind of noise pollution and not good geomantic omen.
