You should pay attention to the following points in this kind of feng shui.
1: Is there no one walking on that bridge anymore?
2: Is your house close to him?
3: Is he facing the door of your house?
The above points are actually the most critical. Generally speaking, the feng shui of being near a broken bridge is not very good.
If all of the above are true, you can place a Bagua mirror at the door of your home.
Of course, if you have the financial resources, it would be better to put that kind of stone lion, or use a Taishan stone.
I hope the offline Bazi Feng Shui 18 Years can help you solve your problems.
