There is a road in front of the house. If the house carries mercury in season, the Lord will make a fortune soon. What does mercury mean in this sentence?

Mercury is not crystal, but crystal belongs to earth; One of the nine purple stars belongs to water, but I personally don't think mercury refers to this. When there is a road rush in front of the house, although there is a saying that "the more rush, the more prosperous", it is aimed at specific situations, such as the road rush to a barber shop (the attribute is gold), because the road attribute is soil, but there is gold in the local area, so it will become more and more prosperous. However, it also depends on the momentum and time of the road rush. If it is big, it will not be more and more prosperous. It is recommended to avoid road congestion. Another situation is that the road rushes to the angry side of the family, which will also rush more and more.
