What does it mean for an onion to sprout in a room from the perspective of geomantic omen?

It means that you should buy two green peppers and a white striped chicken, cut the chicken, wash it and boil it, wash and cut the green peppers, peel and cut the onions, stir-fry the chicken pieces, add soy sauce, cooking wine, beer and salt, taste it, collect the soup, and then add it. When the spicy chicken is out of the pot, just pour the wine.
