I bought a new house in the southeast. I visually observed that there was a power plant chimney and drying tower 1 km away. Does my feng shui have an impact?

You think too much. What effect will this thing have on your Feng Shui when it is so far away from home? It's not like so many people in your own family are not afraid of you. What are you afraid of? As long as it meets the safe operating distance, you don't have to think too much. Thinking too much will not affect your judgment, your life, and increase your psychological burden. So I suggest you stop thinking about it. If you think it really affects your Feng Shui, why don't you move out and live here? If it is necessary to be here, it will affect you. Wouldn't it be nice for your father to go to a better place?
