Hello, the entrance door is facing a long corridor, and there is a staircase at the end of the corridor. What should I do? this situation

The so-called Feng Shui is actually the knowledge of mountains and regulating qi. To put it simply, Luantou is based on environmental Feng Shui, and regulating qi is based on Flying Star Feng Shui. A responsible Feng Shui master will not only eliminate the obvious evil spirits in the mountains for you, but also use the Nine Stars to find out the hidden evil spirits in your home, and find out the auspicious and financial positions in your home. Calculating qi takes longer than looking at the head, at least a day. I have limited energy here, so I will only give an answer based on Luantou. Sorry.
