My neighbor and I went door to door, and there was a long red cloth hanging on the door frame of his house, about 30 cm long. I don't know what feng shui is.

If it is a feng shui layout, it should be to supplement the attributes of fire. For example, there are three blue stars (not stars) at the door. This will not affect your family. What you have to do is to do your own feng shui. Your question is also related to your numerology, fleeting time and geomantic omen. Feng Shui is the knowledge that helps the world. Those who use geomantic omen to harm others and themselves are all fictions made up by novelists. In reality, everyone knows that killing a thousand people will hurt 800 people. Even short-term egoism will hurt Fukuda, because everyone's blessings are fixed, and behaviors that hurt morality will reduce happiness. Therefore, feng shui has always been based on drainage and evil, which is why grams are used as little as possible. I hope it helps you.
