"Two monkeys go up the mountain to be busy for a lifetime" is a horoscope fortune-telling saying, which means that two people who belong to the monkey will be busy for a lifetime if they meet. It implies that people of the same monkey sign should not get married, otherwise they will be busy for a lifetime. However, this statement has no scientific basis and is just traditional customs and superstitions. Therefore, it is recommended that when choosing a partner, you should pay attention to each other's qualities and personalities, rather than just considering the zodiac signs and horoscopes.
