You go and buy a bronze mirror with gossip on the back (around the small 20 yuan and around the big 50 yuan) and hang it on the window facing the street, with the mirror facing outwards. Buy two gourds (about 10 yuan) and hang them by the window. If the economic conditions are good, you can buy copper gourd (around 200 yuan). Check the zodiac calendar when placing it, and choose between 7: 00 am and 9: 00 am on Zodiac Day.
The theory of geomantic omen makes sense, and so does the layout of geomantic omen. But it is ourselves who play the decisive role. Good people have the glory of god, monsters can't get close!
I wish your family happiness and peace!
