The death of the pig-nosed turtle doesn't mean anything, just the normal death of animals. But in geomantic omen, the pig-nosed turtle is considered as the mascot of wealth and blessing, and its death may affect the geomantic omen of the family. In some cases, the death of the pig-nosed turtle may make the family encounter unpleasant things or lead to the decline of family wealth. But these statements have no scientific basis and are for reference only.
In a word, animal death is a natural phenomenon and should not be given too much meaning. We should treat it rationally and take measures as far as possible to avoid similar situations.
