Why is it unlucky to keep giant salamander?

From the perspective of geomantic omen, the cry of giant salamander is very similar to that of a child. Keeping it at home will bring bad things to the home, so it can't be kept at home. In fact, it can also be figured out that if there are children crying every day at home, it will inevitably make people unhappy, make their families very upset for a long time and bring fear. It really shouldn't be at home.
