According to research, there are many successful men whose palms are almost broken, which may also provide some factual support for this proverb. If it's a coincidence, it's a bit far-fetched. According to these real cases in life, it can basically be concluded that men who have broken their palms should all be successful in their careers, but they can't be too absolute. After all, you can't judge whether a person has a future just by breaking his palm.
There are more incidents caused by women's broken palms. In the eyes of the public, a man's broken palm seems to be a sign of successful career, but a woman's broken palm is likely to live alone. In fact, there are not many facts that show that a woman with a broken palm will definitely become a woman who stays in the house, but a woman with a broken palm will definitely reflect some physical problems, such as irregular menstruation.
To sum up, although Duanzhang has his own statement, he can't fully believe it. Especially for men, because many people generally think that a man with a broken palm will have a successful career, it is still ignorant to rely solely on the lines on his palm to decide his future. You should also rely on your own efforts to become a successful man, not just on this unproven statement.
