From the perspective of the Five Elements, Metal overcomes Wood. Metal is strong, while Wood is soft. Strong overcomes soft. Metal can overcome Wood, just like metal can cut down wood. Additionally, it also depends on the number of Wood elements in the birth chart. If there is a lot of Wood, then Metal may be insufficient, and cannot overcome Wood. This is why it is said that women with Wood and men with Metal are incompatible. According to the "Baihu Tongyi": "The reason why the Five Elements overcome and harm each other is because of the nature of heaven and earth. The majority overcomes the minority, so water overcomes fire. The essence overcomes the solid, so fire overcomes metal. The strong overcomes the soft, so metal overcomes wood. The concentrated overcomes the scattered, so wood overcomes earth. The real overcomes the empty, so earth overcomes water." According to the theory of the Book of Changes and the Five Elements, when two people are married, the Metal destiny and the Wood destiny are in conflict. The Fire destiny and the Metal destiny are also in conflict. Those who are in conflict will be victorious if they are strong and defeated if they are weak.
