for me, i follow my moms advice
1. 1 week before i move into the house, i perform home cleansing from sacredsagesg
2. on the date that i move in, i pray to my deity
3. i boil a pot of sweet bean soup and tan yuan. Which is only for occupants of the home.
moms analogy , must remove all lingering past energy from the home so that it does not degrade nor affect us as for the pot of sweet bean soup is to do with good luck moving forward for the occupants of the home.
she caution me that cleansing must be done and that the sweet bean soup and tan yuan cannot be shared with non occupants or friends as they will share in the luck
