Hello .. My father always drinks ... Is there any way in Feng Shui to make him stop wanting to drink?

It's not feng shui. Don't believe those superstitions. My father is dependent on alcohol now. At first, we didn't know that there was alcohol dependence in the world. He often drinks heavily and likes to drink. When he was hallucinating and talking nonsense, our family thought that he had met some ghost or something and invited those gentlemen to do things. In fact, these are all caused by ignorance. By the time we knew it was alcohol dependence, it was already very serious. In your family's situation, what you can do is to give up drinking quickly, otherwise it will be worse.
