1979 August 7th, Gregorian calendar, the fire of life, is Dai Yu suitable for water shortage?

I have to prove it wrong upstairs. First of all, it is to ward off evil spirits, not prosperous wealth. . . Children cry or are afraid of the dark, so they can't walk in the dark. ,,, is used to suppress evil spirits. . . The fire king is not afraid of evil. . . It doesn't matter whether you wear it or not. In the case of water shortage, it is best to wear grass green clothes. . . If you want to wear it, you'd better go to the temple and ask Buddha beads to wear it.
