Because in our geomantic omen, things like shoes and shoe cabinets are unlucky, the new shoes and shoe cabinets you bought yourself are still ok, because they belong to you, so they will only bring you your own luck.
But buying other people's shoes or shoe cabinets is different. Because the shoe cabinet you bought belongs to the old shoe cabinet, and you didn't know his owner's luck at first, because some people will put all their luck in this shoe cabinet and transfer it to others, so that he will let others accept his bad luck or bad luck and get better.
Therefore, when taking you to buy a shoe cabinet, you must be vigilant and never be calculated by others.
