Is it reliable to say that changing money will bring bad luck?

We don't usually talk about picking up money. . . You can't take it on Halloween. . Someone will deliberately leave dozens of 100 change outside that day. The moral is bad luck. Whoever picks it up will pick it up for you. . . We all have them in this building. . . I saw it at the elevator door when I went out that day. . . I thought at that time, put it in front of my house, for fear that others would not think you were a bad person. I don't believe it, but I won't answer it. Shame. . But if you walk a lot that day, I guess you will be lucky to find 1800.
