What is the saying that there is no marriage line

What's the saying that there is no marriage line?

Regardless of men and women, if there is no marriage line in the palm (even very small fine lines) or the marriage line is very vague and difficult to see (the line can be seen, but it is not clear), it generally indicates that the marriage is not good for a lifetime. It is difficult to find a marriage partner. Even if they barely get married, their husband and wife relationship will not be very harmonious, indicating that they will be divorced or single because of Kef (wife) in his later years.
