Among the numbers, 3 and 4 belong to fire, and 5 and 6 belong to earth. You are told to use 3456. It should be that fire and earth are your favorite gods, so you are told to use them like this. It doesn’t necessarily mean you should use it if it’s lacking, and don’t use it if it’s abundant. The main thing is to measure the horoscope and see what your favorite gods are. If fire and earth are beneficial to you, then it is correct to ask you to use 3456. If not, it is wrong.
