Master, I have a question: look at the Shuikou before climbing.
In my humble opinion, the dragon is the main one, see Shuikou. It doesn't have to be evil, but it must definitely be evil. As the ancients said, only dragons never stop. In reality, sitting in the same water with the dragon, the next family will make a fortune, and the next family will be absolutely sure, and vice versa. However, it is against the custom to stick to the water law, one grave and one valley, and five sons enter the examination. So what? Many people in the industry keep the mystery of feng shui, know dragons like the back of their hands, and refer to previous cases because of improper sitting. Shuikou is confused and cannot be changed.
A nozzle does not emphasize multi-directional sitting, and generally only plays the role of left and right shunt. This is just my personal opinion. If you think it makes sense, you can elaborate. Best wishes!
