What does the fortune teller mean by mandarin duck and butterfly life?

The fate of the legendary Yuanyang Butterfly School probably means that the eight characters between lovers can't be combined, two people can't be better, and they can't be happier after marriage. A man's prosperous wife and a woman's prosperous husband, just like a company going public, suddenly began a blowout of happiness.

In numerology, there is indeed a saying that the two sides of mandarin ducks and butterflies can meet on the birthday, and the sky is dry and the earth is dry, which is also called heaven and earth. Couples with this eight-character combination will be as deep as the sea, but once they get to know each other, they will be inseparable, but only once in a hundred years.
