It is best if the owner can burn paper in the bathroom to be rebuilt if conditions permit.
specific methods: choose the imperial calendar, and don't start work on the day when the portrait of life in it collides. Before starting work, burn paper in the room where it started (if conditions permit)
I just didn't pay attention when I moved the bathroom at home, so I had a high fever of nearly 4 degrees a week for no reason. Later, I visited a master and realized that I had offended my father-in-law, and if the ground was not good, it would cause illness.
ps, if you have any questions about choosing a date, you can leave me a message and I will help you!
