Some families, in addition to offering ancestral tablets, also offer sacrifices to God and land. This situation is best arranged according to the method of "heaven and earth match three talents" Divide the wooden cabinet into three compartments: upper, middle and lower, and place the gods' tablets, ancestors' tablets and land in the order of "Heaven, Man and Earth". Some people put ancestral tablets or photos on the counter with idols, which is inappropriate.
Generally speaking, if there is a god in the nave at home, the portrait of ancestors can be placed under the throne of God, not higher than God, and the photos of the living can't be placed with the portrait of ancestors, because they can't be equal!
