What does it mean that two monkeys are busy up the mountain all their lives?

"Two monkeys are busy going up the mountain all their lives" is an eight-character fortune telling, which means that two monkeys will be busy all their lives when they meet, suggesting that people with the same monkey should not get married, otherwise they will be busy all their lives. However, this statement has no scientific basis, just traditional customs and superstitions. Therefore, it is suggested that when choosing a partner, we should pay attention to the quality and personality of the other party, rather than just considering the zodiac and constellation.
