Why the cat’s tenth year is death, the fish’s eighth second is forgetfulness, and the human seventh year is separation.

It’s just a legend. Usually, by the time the rumor (or legend) reaches the tenth person, it may be completely different. . .

9 is a metaphor for the largest number. It contains more essential qualities such as long-term experience and practice, and factors such as being lighter, more agile, and more popular.

If a fish leaves the water (the foundation of life) for just a moment, its life will naturally end; but if a caring person immediately covers its eyes, its life will still be released or survive for more than eighty minutes;

As for the seventh year of man. . . ? There is no need to give one or two examples of actual human life experience; the Seven Elements (Genxiang) may be caused by someone's sorrow and pain when he encounters confusion on his journey the day after tomorrow, but it does not mean that all elephants are like this! ?
