The dragon belongs to Chen, the dog belongs to Xu, Chen is a reservoir and Xu is a fire depot, so it is generally considered that fire and water are incompatible. However, you can't decide everything just by looking at it for one year. There are six red hexagons in the eight characters. If you want to realize this, you must match the date of the month. It would be better if you were in the middle. For example, there are Mao in the two characters, Mao and Xu Liuhe, You and Chen Liuhe. It's complicated. Generally speaking, there is little problem that the earth branches collide with each other. In reality, I know several couples who are six years apart, and they also collide with each other. They all have a good life and their business is booming.
It's just a year conflict, so no problem.
